I know of two others who have built SC in their 8er, and they have reprogrammed their EGS to shift at 6200rpm, but I dont know if that is my solution, maybe there is something else wrong with my car.. i dont know... but i am pretty sure it would fix my tranny failsafe issue.

hi,

rpm limiter in DME and EGS max rpm shift points must be matched up to each other. If your RPM limiter in DME is higher set than the max shift point in EGS and you drive in manual (M) or sport (S), you gonna end up with tranny fail safe mode.

ESS should know this pretty good and have a SC setup file for manual and steptronic versions. If you got a ESS SC DME chip for a manual and use this in your EGS car it will set the failure.

Ask them for the rpm limiter set in your current chip and you will know. Make sure you got a OEM EGS chip to start with. With INPA connected you can monitor live engine rpm or transmission input and output rpm and see the max values and see if it goes over maximum value and sets a code (at least I did this with M62 and 5HP-24 setup and M73 and 5HP-30 setup).

Today i put everything back to stook, except the injectors, just to try and see if the tranny problem still was there , and it was not...

maybe you should give us a bit more info - not every one here knows all components of your particular ESS kit.

I asume you put back:
the NA car's air intake system
the original crankcase vetilation system
removed the resistor in the MAF sensor cable (are you sure it is a 2100ohm resistor/did you measure)?
the original DME chip (# 1-267-357-689) in the original DME.

I don't see actually a big difference to the test you did before (the one when you just put back the original DME chip and you said, it still did show the fault/behaviar with the tranny)??


I checked the .bin files you sent me.

your original DME chip is: sw # 1-267-357-689 (Bosch hw # 0 261 200 404)

The ESS DME chip says: sw # 1-267-358-512 (Bosch hw # 0 261 200 404)

With some other numbers in the file this shows me that ESS very unlikely did your original DME chip "custom tune" for your SC E31 840i.

I would say they did just copy the E34 SC DME chip and gave it to you for your E31.

EGS front and back

from looking at your pictures, I would say someone changed the chip inside (maybe software update or transmission performance software).

BTW: the older DMEs still let you drive "normal" after the MAF failed - they go on fixed maps (open loop).
But they would not put on "transmission failsafe mode".

I think you fried the module or it is a connection failure.

Hello. There was several numbers on the modules . I hope these are the right numbers. If not, tell me, and i will find the right one. Modules numbers: ABS 0 265 106 053. EGS 0 260 002 263. DME 0 261 200 404. There was also a yellow sticker on the EGS with the number : 2 267 010 400. I could clearly see that someone had opened or tried to open the EGS module , the 4-5 or 6 (i dident count them) you bend up around the edge of the module was broken of , i dont know what you would call them in english, but i hope you know what i mean. Maybe someone have been inside it, before i bougth the car , and change something... If you tell me your email adress i vil send you the two bin/chip files . On the first diagnostic readout (after SC mounted) the MAF came up with a error code , in the SC kit there was a resistor (2100 ohm) i should soldering on the signal wire to the MAF , i put the resistor on the wrong wire , the tranny had the same problem in e (ekonomi) and s (sport). I fixed the wire , got it on the right one , then the ekonomi is fine, but not in sport. I know i wrote Previously in this forum that i had fixed the MAF , but on the second diagnostic readout the MAF still came up with an error code. Maybe it is beacause of the resistor, or maybe something is wrong with the MAF...?

hi,

I don't know what exactly you made wrong when you connected the resistor wrong (maybe you crossed the cables/signals) - but I can tell you that a view guys in the US "fried" their DMEs when they connected the cables wrong after trying to do that resistor mod for the MAF signal (additional impedance to lower the voltage for the higher air flow after the supercharger is in).

I am telling you - if you can eliminate a connector issue - get a used DME and EGS on ebay and try it.

Yes where i hade oil service on my tranny . They can read the chip . I vill try to do that on monday . Thanks for all the help , i really appreciate it !

you need to read both in order to compare and please put up the numbers from your modules (DME, EGS and ABS/DSC, on the sticker on the front cover of each module)

I talk to Ess , but he could not tell me year and month he based the 540 chip on , he dident know , and he couldent find out..

That's BS - year, month and software number (BMW and Bosch and Damos number) is in every Bosch file for a BMW DME.
If he reads/opens his original (ESS) modified E34 540i SC file, it is clear written in (in hex).

If you got someone near you who can read your OEM chip and the ESS chip and you send me these .bin files, I can tell you the difference of the two or if they are the same software number.

I have considered to converted to manuel transmission , but only if i have to. Do you personally think my 5hp30 is to weak for the SC power , that the problem is most likely my tranny . My car is driven 188000 km.

no - the 5HP-30 can handle the "regular" ESS kit. It is factory rated for 560NM - so no problem with your >550NM from the ESS kit.

the easiest for you would be to test a different OEM DME and OEM EGS.
They should be easy and cheap to get on ebay. Afterwards you could sell them again. Try to eliminate a connection problem first.

Don't rely on cheap old code readers! Get a BMW specific laptop based ADS system with INPA and/or DIS. It's cheaper and much less stress in long run.

Was at my lokal workshop , deleted all error codes, they could only read the DEM.

if they could not access/read your EGS than there is a problem already. DIS or INPA should be able to read EGS.

Does your local shop have an original diagnostic machine like Modic or DIS/GT1 or newer or a laptop ADS system?

Does your M60 really have four knock sensors??

All failed at once - I doubt this.

Even when you disconnect all knocksensors - your car would still drive and shift normal. DME will go on different maps (pull back timing).

If ESS chip and OEM chip act the same way (same errors) than you got a problem with one of the modules or connectors.

did you have the issue already before you installed the ESS kit?

could it be that you damaged the DME when you pulled and installed the DME chip (for example static damage)?

ESS did not know on what M60 car (model and year/software number) they developed their M60 kit??? That sounds strange to me.

Do i need to drive the car into the tranny failsafe when taking the readout ?

Yes, in order to get an idea what is going on in your car we need to read the erors after the car went into transmission failsafe.

For example for issues I had with DME/EGS errors:
When I had an incompatibility with software numbers (EGS-DME) the error message came only after I was driving a while, since the error is not set instantly because the software tries multiple time to confirm the correct number and only after multiple times of failing (at least for these modules around these years) it sets a error and displays the "tramnsmission failsafe" message in OBC. Same was valid for checksum errors.

But be aware that if the same errors happen with ESS DME chip and OEM DME chip - your problem is caued by something else. If you change DME chips back and forward - you have to reset all errors otherwise the error memory still contains the errors that were saved with the other chip sitting in module.

I will go to my lokal workshop and get the readout on my car . I will try to do this asap. But maybe not before next week. I hope you can help me then .

if you have to go to a workshop to read out your modules - it will be a pain to do all the tests.

I highly recommend you to get an INPA ADS system (or at least DIS ADS system or a code reader) when you play with supercharged BMWs.

Also put in a boost and AFR gauge into your modified car.

Do you need these numbers ?

just put them up here, so we will know what we talking about - and also your exact month & year or least seven digits of your VIN number and the ESS chip they send you (for what year & month of E34 540i)

Ess told me to try the original chip , but that dident change anything ..

hi,

SC = SuperCharger

you have to be more specific or no one can help you.

first: reset all errors in both or all three units (DME, EGS and ABS/DSC)

second: switch on ignition and read all three modules out (look for errors)

third: start car let it idle and read again for errors

fourth: start car and drive around and read for errors

do above with ESS modified chip and with OEM DME chip.

Be carefull when idle/drive your supercharged modfied car with the OEM DME chip (I wouldn't really do it - but since ESS told you to do so - I guess they know what they do/recomment). Just make sure there is no chance to run it to lean!

let us know what happens in all stages.

I don know what you mean with SC , but Ess know it is for a e31, they did not read my original dme, they only sendt me a chip . The number on the gearbox i have to check . Do you know where i can find it, is it on the gearbox, do i need to get under the car ? I will try to find it tomorrow .

all numbers are on the DME and EGS module (on stickers)

I have been in contact with Ess more than ones , and he have sendt me a new chip to the dme , dident help, then he sendt me a bigger wheel to the supercharger, dident help, waiting for a new chip to the dme from Ess now, he know my problem very vel, but he cant help me with egs software ..

ok - first check or let ESS or someone else who can read your DME (or memory) if the modified ESS DME chip has same hardware and software number in memory content like your old OEM DME chip.

Did ESS just send you a SC modified E34 540 DME chip or did they read your OEM DME chip and modify this memory content with the maps for the SC setup?

Do you have 5HP30?

Zitat von TERMINATOR;92312

If i need to modifiy EGS software , who can help me and do that ?

hi,
first check, if you really have to do so - if yes - talk to ESS, since they made your kit and also do some EGS programming for other EGSs too.

With your setup (6-7PSi and around 400hp with >550NM) I would run OEM tranny software

When i hade oil service on the gearbox they tok a diagnostic readout. I dont understand much of it, but here it is : (067) 43 knock sensor 4. (041) 29 air-mass flow sensor (hfm). (155) 9b load signal info. (201) c9 oxygen sensor control 1. (041) 29 air-mass flow sensor (hfm). (203) cb oxygen sensor control 2. (067) 43 knock sensor 4. (012) 0c oxygen sensor 2. (104) 68 over-revving lock. (016) 10 rotation speed signal turbocharger. (155) 9b load signal info (150) 96 can time-out 1, ignition on. (02) connection to ads malfunctioning or fault in area of throttle-valve actuator. (06) wheel speed sensor, front right. (05) speed sensor, rear right. hope some of you know what this means , or if you kan see why i have problemes with the gearbox . THANKS FOR ALL HELP.

hi,

way to much errors. delete all and see what comes back.
over reving, CAN time out, wheel speed sensor and speed sensor all are related to ABS/DSC/EGS and could cause a tranny fail mode.

I am not sure with M60 but with M62 you could get issues when you put a DME that is supercharger modified for a 5series or 7 series into a 8series even if the hardware (engine and EGS) is the same. Just to mention different memory content / maps. And even if it worked in one car/year it could run into issues in a different model year. Check with ESS if your modified DME software is designed to run with your OEM EGS software.

For example: If an OEM EGS software detects a non plausible DME number it sets a fault and goes into tranny emergency mode. this could happen if you put a modified chip into your DME with a different software number (the engine would still start and run fine).

that is why I asked for OEM software and hardware number for DME and EGS. Make sure the modified DME chip is working with your OEM EGS software.

I only experienced problems slip/shift related when going over 6-7PSI and setup over 400hp and going higher then 6200rpm. I had to modifiy EGS software as well (EGS 8.55 5HP24).

If you have the 5HP30 - lucky men - this tranny takes way more torque

This happens without losing traction , but the light for losing traction and the abs light is on, all the time..

just saw this post - this is actually a bad sign.

Are you saying whenever you start your car and drive on you have from the beginning both lights on?
what is your rear axle and wheel setup?

OEM hardware for DME and EGS?

firebird

Hi,

please post more info about engine / tranny hardware and who did the software for the DME and EGS?

Modified DME for supercharger setup and OEM tranny EGS could run in a lot of problems especially if over 400hp and 550NM (BMW M60/M62 V8).

thx

is my engin and autmatic gearbox strong enouge to handle a kompressorkit from esstunning ? does enyone have some experiens with this?

Hi,
M60 or M62 engine?
5HP30 or 5HP24 tranny?

I don't have the ESS setup but similar with Vortech V2SQ.

The engine is not the problem, it is the tranny. If you got a 6speed - you are open for the "full" setup.
Don't forget the LSD - 2.93 or 3.15
If you are looking for more than 400HP get an intercooler or W/M injection.
If you don't have it - better monitor really good AFR/EGT.
Otherwise the V8 is a bulletproof engine to supercharge and fun to drive.
I am riding the above setup in a Euro E39 Touring plus with race cats, MSD delete and Supersprint exaust and modified tranny EGS (quicker shifts, rpm to 6500 and WUK earlier/less stress). Depending on software setup and pulley size 430 -500+HP (with regular cats and exhaust it starts around 410HP).

Forgot - the suspension and brake upgrade - went all with M5 parts (pretty cheap compare to Brembo) and Bilstein B6 (or B4 have to check)
I am actually on my second rear end - the tourqe is awsome. Once I am back in Germany - I will upgrade the tranny internally (unfortunally the 5HP24), since I can hear already how it is suffering - but I push the car hard some times :-).
