well, it could just be weak valve seals, or rings. Are you loosing coolant? Is your oil looking ok? These are tell tale signs of BHG, low compression can be caused by many things. If you are losing coolant, then dont drive it, unless you want to be stranded somewhere.

i grounded mine to the battery, which happens to be located in the trunk. But i also ran a ground to the rear seatbelt bolt after cleaning the paint off the surface.

that is the only difference, you could also relocate the srs ecu as i did on my 91. just opening options.

yep, you will get there. I have very similar mods but tuning with afc neo on blitz ecu with aristo 440's and made 450 hp at the wheels. Good luck tuning!

Ive used 2 ecu's actually... one mines tuned ecu and one stock ecu, both to the same effect. Ive played with my fp a ton, from 35 to 55 lbs, same thing. I a have my walboro 12v modded as well. Oh, the ecus are from the chaser, it was a supra half cut from j-town. Thanks!

Sorry for the lack of clarification... The fuel pump is a Real Walboro 255, it is 12 volt modded directly from the battery and wired by a relay that i installed. There is no dip in fuel pressure throughout the rev range, even while boosting the pressure will just increase.

Ok, apparently i didnt update this thread. I have not gotten the problem resolved, The guys at IPS Tuning were not able to tune the lean spot out, even addin 50% fuel at 3000 rpm didnt resolve the issue. Im Really stumped now. Any suggestions?

1. I dont think im hitting fuel cut, my ecu has no fuel/boost cut. 2. Im not sure, which wire is the tach singnal? my tach works and everything... not sure. 3. Im dont know that there is no injector pulse, i just know that there is almost no fuel, the wideband goes full lean, and the guy at...

Yes sir, it is. Thats a really good thought though, thats right around where it switches from 8 to 12 v. I watched the FPR gauge while on the dyno, not a single fluxuation, until boost set in then it just went up... Good thought!

Ok, so after Trying to get the car tuned at IPS Motorsports in Columbus, OH, I found out that the issue is not ECU related (i think) Basically at 2850 rpm the fuel map just drops, NO injector pulse width... We tried adding 50% fuel at 3000 rpm with my SAFC NEO with no success. Basically...

I would just go to the bank, take out 600 bux, then buy a hks super dragger. Resonators are a good idea, without them you get a real bad sound, at least in my opinion.

the injectors not firing is usually a cam angle sensor... the rear (i believe) controls the injectors, there are 2 pickups on the intake cam, one in the center of the cam and one on the back. Just a thought. Good Luck!

cranked the FP back up, no progress... Im installing the NEO today and am getting it tuned tomorrow, hopefully they will be able to tune it out! THanks for the input!

Im going to bring the fuel pressure up to 44lbs, between what Bigzavs and gotturbos recommended, ill report results later today!

I just got back from the shop, i installed an AEM Tru Boost and and AEM UEGO gauge in the car today... Since the single swap i have noticed a "dead spot" in the rpm range, from `2850 to about 3100 rpm, the car will barely accelerate through this range. After installing The wideband i can...

Thanks for the reassurance Tissimo, It turns out i do have the 440s installed!

What color are the injectors, i believe that i have confused the 3 sets of injectors i have floating around, Im pretty sure i had installed the stock injectors , but im smelling raw fuel in the exhaust so im second guessing myself. What color are the stock injectors vs. the Aristo 440's...

I absolutely LOVE my Super Dragger!!! I wouldn't trade it for anything other than a titanium exhaust (its freakin HEAVY!) I love the deep rumble, almost silent at idle, but WOT sounds GREAT! HKS Super Dragger FTW

Well, all the problems were resolved when i re timed the damn thing. Thanks for all the help guys! I really appreciate it!

i reccomend using the dampener bypass hose from DM, Its awesome, and super easy to install, and one less junction in your fuel system... Just my $.02
