gotcha

 

yea the open WG rule is stupid I agree. And the 3.5" rule is tight too. Heck just out of curiousity I measure my road clearance and it was right @ 3.5" lowest point.... my car isnt that low really

 

It was at 4". But I thought the last revision was 3"? I will have to check my height nonetheless now though.

 

Thanks Dawg, if I get a o-scope, that'll be the one. I've never needed one before and probably never will again so that scope is priced right. I thought of a potential problem though. Since the misfiring only occurs at high rpm, won't it be difficult to test without a dyno or someone riding shotgun to monitor it? Or can I log the readings?

It's possible although I have tested two different 1910s and Martin hasn't had any issues with the one I sold him. I think it's more of an incompatibility between the 1910 and my crk/cam sensors/ecu. It's a fairly common problem posted at the AEM forum, usually with no help offered by AEM. Maybe a new crk sensor would help but I tested mine per Toyota procedures and it was within spec. It also works perfectly with the FIC bypassed.

Thanks. If the Ultimate can clamp my MAF at various rpm breakpoints, control the injectors, modify the O2 signal, delay my crk/cam signals without screwing them up and not throw any CELs, it would do the job.

BTW, it's pricey ($250) but URD has a AFR calibrator that reportedly does a great job of modifying the AFR sensor signal for CL tuning.

FWIW, I'm really enjoying the car again without the buggy FIC. It runs great without the FIC and open loop AFRs are between 11-12:1 in boost. The only major problem is a recurring P0101 with no MAF clamping.

How about Unichip? A friend offered me one to try. All I know about Unichip is that I dislike the lack of end-user tuning. Is Map2ECU any good?

 

This is critical info for me! Thanks! If I can run 6psi without pulling timing, I can simply rewire the FIC so it doesn't intercept the crk and cam sensors and solve the problem very easily. I would just tap into the crk sensor for rpm and be golden.

BTW, we can rule out bad sensors, harness, loose pins, etc. The car runs perfectly with the bypass harness installed, with or without resistors. Plug in the FIC and my crk/cam signals are distorted by the FIC every time. I can't rule out the possibility that my FIC is bad but having had the same problems with two different FICs makes it fairly unlikely that a third FIC would do the trick. IMO the relatively narrow window of crk/cam sensor compatibility of the FIC is it's achille's heel. Greddy doesn't have 4 different Blue/Ultimate models to handle different crk/cam sensors as AEM does. Then there's AEM QC... but I won't get into that here.

 

hey was meaning to call you today but thought u would have been at work till late, i thought my sputtering around 5800-6000 rpms was related to timing so i pulled some timing and that was a temporary fix, last night i got sputtering again...


today i decided to remove the resistors..... car was not idling too happy was hearing misfires but it drove fine and no sputter up top...... i then decided to put resistors back in but after installing just one which was the cam resistor and car is flawless now just thought id share that with you seeing as i know u had some luck with just 1

 

The fact that any resistors are ever needed to bandaid over inherent FIC flaws says a lot about the FIC. OTOH, it seems to be a great bang for the buck piggy when it works. Maybe AEM should just include a pack of various resistors, a soldering kit and an oscilloscope with every FIC?

I sincerely hope that your new FIC wiring solves your FIC caused misfires. FWIW, AEM has told me several times that resistors are rarely needed yet I can't even drive my car without a 2.2k on the cam inputs. I could drive it with a 2.2k on the crk but I couldn't rev past 5000rpm.

BTW, I talked to Toan at P-Tuning today and he said they don't get into oscilloscope trouble shooting. He was very helpful and gave me some other options to consider. I'm not sure yet what I'll try next.

 

i think i may try pulling my resistors off too. its weird though cause my car drives fine but i just get random crank/cam codes.

 

Good luck with that. I really hope you can find a way to stop your FIC from screwing up the crk and cam signals. I'll bet my FIC against a E-Manage Blue that bypassing your FIC would solve your crk/cam code issues completely.

 

so from reading all this i was tryn to find an answer but this was all confusing seein how everyone prefers a different management. I wanted to know which would be best for me to use with my supercharger the Greddy Ultimate or the AEM FIC?

 

The S/C works off of RPMs. The more RPMs you have the potential to make more power. The Ultimate can raise your RPMs, the F/IC can not.
