hay every one,

2 quick quistion is it true if you get a aftermarket computer,pfc/heltec/motec/ems/ect,ect,ectin the r34

do you loose the function with the :Traction Control

I ask cos i got a new ecu put in,then he told that i will loose this function

an also the engin light,the tcs,an the slip lights in the dash permanently stays on

is this right or have i been screwed an he has'nt done it right

also now it takes about 4-7 sec to even start,

were as before it turnd over straight away.an when it does start the frist three sec it sound like its going to stall

after that it goes to 1500 revs until it warms up then drops to 900 revs

does it sound like he has'nt tuned if properly

thanks

did you get a new ecu or just a chip? I got a chip & tune done in my R34, and NOT a problem in the world with TCS or start up. take it to get looked at by a new workshop and a new tune. may make ur car run better & they may find the reason why ur TCS isen't working. and the slip light woulod be shitting me off if it stayed on.

"IF" the ecu has stuffed with the TCS and wont work again, get some wire snips and cut the wire to the Slip light asap. haha

Where'd you get yours chipped if I may ask?

Sounds like a few minor issues. I doubt TCS will work as the stinger doesnt appear to support it. You may have idle issues.

Why dont you ask the shop why it doesnt start up as fast as before and why the lights are always on? If you did then what did they say?

you have to check if the ECU has Plug N play base map on it. If you use chip in your stock ECU or aftermarket with plug N play such as PFC, then the should work fine...

My guess is your car is tuned with ECU which does not have a base map, the ignition delay is caused by poor cold start tune. It is easier to tune while engine is hot and running however cold start is tricky, as by the time the tuner got the approximately right tuning, the engine would have been warm. Then to wait for the car to cool down again takes 2-3 hours, which I highly doupt the tuner will put the car back on the dyno.

This is also consistent with your idling problem, sometimes if the tune is not done properly the car will actually stalls on its own, you got to give it a bit of fuel... you won't have this problem once engine is warm no?

Hmmmmmm, sounds just like the problem I had when I had a Microtech installed. No AFM causes heaps of things to not function as they should. Changed to a PFC with a Z32 AFM and bingo all is good again. Does yours still have the AFM?

it may be that the TCS/ABS computer required signals from the ECU , such as TPS . This is similar to how the auto works .

This means those signals must be replicated by the ecu (which the r34 pfc would do) or you may be able to bridge the sensor outputs required for TCS . this is often how other ecus such as motecs and autronics are installed to work with tricky features like traction control , automatic gearboxes , stability control etc

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
