Sup guys?
Sorry for my english, if i'll make some mistakes.
On to the problem: I blew my HG a couple of years ago (Maybe previous owner did it, but I found this), rebuilt motor with arp studs, metal hg, new pistons, rings, gaskets, plugs, plug wires, rc 550s, aeromotive afpr, MAFT Pro with speed density, walbro, constant 12v mod, new big rad with electric fans, new thermostat, new ECU temp sensor and I replaced a feet or two of wires going to it. My base fp is 35 psi vac off, 25 vac on. Reset timing a million of times. It jumps around 10 btdc, 9-11, but 10 most of the time.
I start the car and id idles with 12,5 a\f, can be 10 - 11 a\f. My vf shows 0v until the car is fully warm, BUT it showed voltage a couple of times almost after my temp gauge reaches some bars. Anyway it's not 30-60 seconds as it should. My vf is something shitty. As the car warms up it shows 2 volts, everything is fine, but then the miracle starts. Yesterday I read a pimptrizkit's comment in this post http://www.supramania.com/forums/showthread.php?39712-MAP-ECU-Tuning/page3&highlight=vf
My mainscale was -12 (At least it was driveable, but a\f and vf jumps constantly), and vf showed 0v, soooooo, I started to decrease fuel. I change to -15 - cool 2v, then after some time it is 0 again. -18, again 2 volts, then again it shows 0. DAFUQ? So I made my way to -21 mainscale AND to -21 Low Load @ 800 And voila! 2v almost all of the time. It can show 0 to 4,4v. I came home, opened beer and sat in front a tv like a bau$, being happy with my victory. Today I started the car and it idles at 12,5 a\f. With -42 fuel (mainscale and low load @ 800). WHAT THE ACTUAL F#*@??? When the VF came on, it started this shit again, but in opposite way. 4,4v. So I started to increase fuel, just to find out i'm on -12 mainscale and 0 at low load @ 800. I cant tune it, every time is like russian roulette. I'm sooo fuc*ing tired of this car, that I'm thinking about a JZ or an MR2. Im so tired of this 7m VF afpr mainscale a\f misfire stalling reseting timing clearing ecu codes SHIT!!!!!! I bought my car in 2009, and i cant drive it like a normal car in 2016. That's just shit. No codes, everything is fine, but it can just switch to 10 a\f and drive that way. Wired my MAFT with schemes that came with it.
Wiring? CSI? ECU? What can it be? I cant tune it with maft pro, it just doesnt have ANY logic. I'm trying to satisfy VF, but I simply cant.
Please help! Thank you!
