Ive been searching for the past couple of months to tune the Motronic ECU but can not find enough info. I have the ostrich 2.0 and a chip reader/writter.
I can edit the fuel maps but I dont know how to add boost maps. I've been trying to research this forever staying up till 3am searching still cant find answers.
How can I datalog from the ecu if possible how can I tune fuel maps for boost. I know I need new maf. I just want to get the ecu problem figured out.
I used to have a turbo civic I built and I tuned it via chip in computer with live datalogging. It used same chip as motronic DME so I still have the hardware I used left over from the civic.
I have a 92 325I that I plan on building and turbo charging for 600hp. I can do everything else no problems but I need to figure out the tuning problem. Are there any standalone ecus for these cars? Or can I somehow tune the oem ecu and make it run right with boost?
Any help appreciated. I searched for a long time already so please dont tell me to search on google. Just need some options.
Your best and probably easiest bet man, is to ditch that ecu, use the factory 325i one and get the miller w.a.r. chip. You can tune it urself with no issues. I had that chip in my old turbo 94 325i with 720cc injectors, precision turbo, hks bov, fmu, factory bmw fuel pump, and i was able to put down a nice 420 on 22 psi high boost. I ran the car daily on 16 psi. stock bottom end and heads. only reason i got rid of the car was due to rust issues.
I read about the war chip. Does it have datalogging? How do you tune without? I do have stock ecu. Motronic
stock motronic cant see boost...
thats the limitation of the stock MAF i believe
thats why most go aftermarket or aftermarket MAF
or real budget people run the MAF pre-turbo
either way, stock MAF is only good at measuring airflow upto something like 350bhp and then its pegged full

There are so many great standalone solutions for OBD-I E36's that I much prefer over trying to use stock or reflashed stock components. Sure, you pay more up front but the time and energy saved by proper data logging, the ability to control the tune completely and the turbo-specific engine safety strategies pay for themselves.How can I datalog from the ecu if possible how can I tune fuel maps for boost.

I know stock maf can't read boost. I'm doing porsche maf. Please give me list of stand slimed for e36 obd1. That's all I want. I found one for 3k but a little too much. I know megasquirt but it's a lot of wiring to do that I don't think is a good idea. Thanks!
megasquirt isnt really a lot of wiring tbh...
i built an adaptor out of an old motronic box, cost me about £5 and a few spare lunchtimes at work.
Plug and play, swap between stock and megasquirt in literally 2 minutes on an e34.
anyway, thats my wander slightly off topic

5mall5nail5 can build you a bamf megasquirt setup
im going to be running a dta set up- radowski makes a plug and play set up
aem setup- radowski makes a harness for plug and play set up
False, well true in some cases. The stock mag has been know to make ~350whp. Such as my old AA stage 2 kit.Originally Posted by uk525td
This is my signature....
Where can I get a wiring diagram for the AEM and the megasquirt? Im thinking aem right now but just in case I change my mind I want to have both. I want to make the harness myself.
Also if I do a standalone AEM or megasquirt will I be able to use the factory sensors like O2 to get good MPG? I could care less about the mpg Im just asking to see if possible. Id like to have the car running as much stock like as possible without check engine lights.
on megasquirt, yes you can run with every factory component, o2 sensor, CLT, IAT,Crank,Cam etc etc
but in all honesty, youll end up fitting a wb and controller, or if oyu didnt, you'd be considered clinically insane...

Ok thanks for the help. Finally starting to work on my dream car. A little at time of course. Running a small business and building bimmer is a little tuff. Ordered Megasquirt today.
One more question. Is there any other mafs out there besides porsche and war? just want all the options I can get.
if you've ordered megasquirt you dont need a MAF (but you can run one if you so desire)
what spec of megasquirt have you gone for?
More useful than the bentley manual is the electrical trouble shooting manual
i found the manual for my e34 by googling e34 etm pdf
it should also apply to your car too assuming its obd1 on bosch management

I got ms3 vs3.0. Should I get the 3G adapter or is it not needed?
So you selling the Ostrich now?
lol no sorry. I dont tend to sell stuff. I had it lying around for a year and a half now but Im sure I'll get another civic one day. I have the whole kit. chip burner, emulator, and datalogging.
I dont know. I'll think about it.
I meant MS3x expansion. Iphone spell checker. Should I get it or not worth it?
