Driving down the road and stereo lights start flashing off and on plus dash lights. when I shut car off and try and start again it does nothing, starter doesn't even click. Also have no dash lights or anything inside car electric, headlights will come on though. I pushed the car off and it ran...

Today I go out to start car after one day of not driving it and it wont start. Engine will turn over fine but just wont start. I think its getting fuel because I have pressure on the fuel pressure regulator gauge. Ive also noticed that there doesn't seem to be a metal contact on one of the...

Ok I have had this issue for a while now. Under 3 thousand rpms while at wot My car runs lean. I have the fuel pressure at 45psi(vacume not connected) and im adding around 25% on the safc in that area of rpm band. At these settings im still at like 12.3-12.5/1 air fuel ratio. As soon as it gets...

I searched but didnt find exactly what I was looking for so... Anyway, over on SF there was a thread on a guy logging his timing on stock ecu with different fuels. pump 93 , a toluene mix and 105 race gas. He was seeing how much the ecu was pulling timing with each fuel at different boost...

Lately since the weather has been cool my boost has been over shooting the target level. It will rise to the target boost level and then around 5000rpm starts to creep 4 or 5 psi past it by 6000rpm. I use a greddy profic b ebc for boost control and a 38mm tial waste gate. I wouldnt think the...

My autometer boost gauge and my ebc are showing two different boost readings. For example, when my ebc says im boosting 14.6psi, the autometer gauge says like 16psi. Is the autometer considered an accurate gauge? wich is likely to be right , the autometer gauge or greddy ebc boost display? Right...

ok other than being crap, what would make a clutch fan work in reverse of the way it should. When the car is warm sometimes the dam fan will be just be free wheeling, and temp goes up. At other times like last night when its 60 degrees out, the dam thing wont shut off while driving, its blowing...

posted this in HPF section but got no response. my motor has a fully built bottom end and I have a sp58gt turbo. Right now I can notice a fall off around 6 thousand rpms. I have no head work except a 3 angle valve job. I dont know much of anything about cams so here is my questions. 1...

Lately I have been looking at turbos and trying to get a better understanding of things because I have never fully understood everything about turbos. Thing is im getting mixed up on what is what on wheel sizes. what do most people classify the turbo compressor wheels by, inducer or exducer...

OK I have been runing between 15-16psi on a sp58gt HO but wanted to turn it up some. Tried for 17psi, did not hit fuel cut but afr's was to rich, had taken out up to -18% air flow signal with afc and was still rich in upper rpms. At this point I didnt want to take out any more signal with...

Today I wanted to lean my car out some, runing rich at 4 thousand rpm and above. I have 12% on afc taken out at those rpms but still below 11.0-1 afrs. The thing is I dont want to keep taking fuel out with afc because of the effect it has on timing. When I lower fuel pressure my vf readings...

No kill but the old mk3 made me proud today. Was parked on shoulder of on ramp to interstate making a call on my cell this morning. As soon as im off the the phone , I see a red c6 vette speed by getting on the interstate. Im like what the hell and take off after it for some fun. When I...

O.k I have had my fp set at 33psi, vacume connected. AFR's at idle 14.7-15.3 and at wot, low 11s. Today I checked my vf's, at idle it was 3.53vf with 14.7-15.3afr. I have attempted to adjust this by adding fuel with FPR. No change in vf's when I go up to 35psi on FPR. The vf's do go down to...

just checked my ignition timing today, it was off a bit. when I attempted to bring it back down to stock it would go no lower than 15 degrees. I pulled cam sensor all the way up with e1/te1 jumpered and it will just not go lower than 15 degrees. could cam or crank timing be off? Another funny...

well I just had a 7mgte built for my 89 supra, problem is I think the head gasket might be leaking but I hope not. The motor now has 800 miles on it, today when I started it, I noticed a white steam coming out the tail pipe. Didnt think much of it since it was morning and figured it was just...
