The ECU warning light on my 34 has started turn on. Its the one on the top right of the speedo. It only comes on about 5 mins after the car is started as if an error is only detected after the car has warmed up. Anyone ever had a similiar problem. Wondering whether the SAFC is messing up the ECU. Car is going in the shop next week but was wondering if anyone knew about what could cause this. The car seems fine and is running without anything noticeably wrong.

Thanks Ben HPI. I was told that by my mechanic ill get it checked out next week. One thing though, my mechanic wants me to disconnect my SAFC casue he thinks they are not worth the hassle and he doesnt want to tune the car with it on. Should i change mechanics ?

By the way HPI rocks

are you sure its the check engine light??? is it the oil light??? checked oil levels lately???

some sensors may be malfunctioning, for instance your AFM? maybe try some contact cleaner on it?

goto a different mechanic. the fool obviously doesnt know what to do with the safc. they will be a tremendous help when properly tuned. and you know you can default your safc back to zero's and essentially let the ecu run "factory". ???

ben,

what do u recommend for the R34 without touching the internals?

What do you mean? Just a turbo recommendation or a whole package? Are we talking about a GT-t? What do you want from the car? I can't make any recommendation without this sort of info

    • Hi All, I'm based in Sydney and want to get hold of 4 stock R34 GTT wheel caps as pictured. Cheers
    • Haha im flattered! Although my poor boat is collecting dust in the garage, as it hasn’t been driven in like 6 months. I forgot the to put the trickle charger on too, so the battery is likely toast now.. I have the frenchys kit. It is fantastic. My only gripe was that the hard lines from the firewall needed some tweaking, however, this was mainly due to my specific turbo and dump combo. The weight and size packaging is much nicer too. I think I have some pics on my build thread somewhere.. my justification for the kit was more “why not” I had gone to the trouble to modernise just about every other part of the car..
    • Actually, ethanol has probably never been cheaper, on a tax free basis, than petrol. With fuel excise being what it is, and only being levied on the hydocarbon component, not the ethanol component, and ethanol for non-drinking purposes not being subject to liquor excise - E85 was cheaper, but not because the combustible liquid itself was particularly cheaper.
    • Maybe? If changing the cat to a higher flowing cat, caused the turbo to spool more quickly, and those areas of the map had not been tuned for the boost level it is now seeing, then yes you would need a re-tune. How dangerous it is running without the updated tune would depend on how far out the tune is with the now higher boost levels, how the engine protection has been setup, is the ECU compensating with a wideband sensor, is the boost control closed loop blah blah million other things... But yeah having said that, I wouldn't be surprised if changing out the cat for a high flow, in say a full 3" exhaust, made no noticeable difference at all. 
    • Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.
