I'm probably splitting hairs here, but as you said the injector pulse will still be the same, so with 550s and 20% more fuel pressure, you will get 45% (or so) more fuel for the same pulse as compared to 440s and stock pressure. So with a non-functioning air measurement device, the amount of...

Not at all - MAFT transalator (not pro) with 3" GM maf, AFPR (don't remember where I have it set, but above stock pressure), 550 injectors, upgraded supply/return line, MKIV fuel pump. MAFT was tuned and working well with injectors and fuel pressure. I haven't made any changes there. My...

OK - it won't run unplugged either. If I unplug it, it acts the same, except it will then throw a light. If it's unplugged isn't it just using default fuel map? I have 550s with elevated fuel pressure, so if it is just using the base map, its getting LOTS of fuel... No - I haven't...

OK - thanks, guys. Just ordered a dmm capable of frequency and I'll measure. I've tested almost every component I can think of that would cause the problem - just seems like fuel isn't being metered correctly. I have nothing to base that on, though. Don

Is there any way to measure the output of the AFM without an ocilliscope? I think my MAFT is not working correctly, but I'd like to see what is being reported to the ECU to verify. I do not have any codes, the engine will start fine, but will die within 3 - 10 seconds. Applying the...

No - the only way to drive it is to (try) and rev the engine to 4 or 5 grand (will only do it every 3rd or 4th attempt), pop the clutch, keep your foot in it until it dies. Then, repeat and go another 15 feet. TPS is new (year or two - 1500 miles or so), but I'll give it a check. ICSV =...

Thanks, SupraFanatic. I've checked all the IC connections (have hard pipes) and all are good. Good idea - I haven't checked the VFs. I'll see what the computer is reading....

Car cranks fine, and will idle for 3 - 5 seconds completely normally. Then, it will start to die. Somethimes it will recover, sometimes won't. Pressing accelerator will sometimes keep it alive, but will eventually die. Feels kind of like a big intake leak, but have inspected and can't find...

I just bought some rubber transmission oil cooler hose 3.8" from advance auto. Cheap and easy.

For posterities’ sake, the answer is 3/8”. Changed mine out tonight, and appears to have resolved my leak. The old ones were most grubby and oily. Don

Any one know the size of the stock oil cooler hose? Mine are leaking badly, and I want to do a quick replacement so I can drive the car once in a while. I'm going to do a complete oil cooler install, tstat, braided hoses, etc when I install the new engine, but just want to replace the lines...
