Its the MAFT Pro wiring, cuz disconnecting it worked. The car idles just like a dream. If i could find the adapter from lexus AFM to K&N filter i could just remove MAFT for a whie. Nice toy, but i really starting to hate it.

Well, that didnt help.

I did it already, but thanks! Well I found out one of my points in VE table was 0, so i fixed it, will see tomorrow how it reacts... Strange shit...

I can upload my Bin if it will help.

Hi guys! I was trying to find out my misfire problem. Most of the times it occurs when the engine is warming up. But sometimes i get this misfire while waiting for traffic light (And sometimes it dies.) I was trying to tune my MAFT PRO with a laptop, satisfying Vf and smoothing the VE table...

Well, found my problem. I made an additional ground to MAFT PRO some time ago while troubleshooting other problem and now it started to interfere with the original one. Disconnected it and now everything is fine.

Searched some stuff and found out it could be a bad ground. Will investigate.

Greetings guys! I have a MAFT Pro installed, running speed density, everything was ok. But. Sometimes the VF voltage starts to get weird, instead of 1.25v (Well i never had 1.25, more like 1v) i get 0,5 - 0,7v constantly jumping around and stuff, but it should be in steps. And it seems that...

Thanks for replies guys! I've set CPS a thousand of times and used this second guy's comment. http://www.mk3supra.org/topic/958-timing-issue/

P.P.S. When i apply throttle, it become more stable as i think, but really bad misses, i hear a ~5-10 misses a second on ~3500 RPM.

Hi guys! So i've got this troubles with my car: When i start it up, it fires, works like a charm a second and starts to sputter, idle oscillates, smells fuel like hell, very advanced timing (With Te1 and E1 jumped - far more than 15, maybe 25. If i unscrew the CPS and turn it to maximum, it...

1. Timing belt is new and did ~1600 miles, CPS bolt was fastened hard. The moment it changed timing was just 5 minutes when i was on the gas station. 2. Timing was ~10 btdc, it was jumping a little because of old wiring before i repaired it. 3. Yes, its brand new OEM Toyota, wiring was fixed...

The new CPS wiring seems to be working, thank god :)

I wanted to do as f00g00 said, but all that stuff that i did seems to work.

I've got an update: I made a full lenght new wiring from ECU to CPS, installed new wiring for coil packs, repaired connector and couple of wires, deleted CSI and Fuel pressure up VSV, reset timing, reset fuel pressure again to 37 psi, set -20 mainscale and voila! It runs much better, although i...

Hmmm, never thought about it. Genius! Thank you! I'll try this. Have a Lexus AFM laying around somewhere, but my wiring for AFM is sh*t, but I'll fix it.

Too bad You havent resolved this issue( So you was driving it like that? I made a fully new wiring from cps to ECU, but it didnt help. The wiggly cps wires are repaired, so it is more stable, but the problem is there. It idles between 13,5 - 19 AFR. Then it can just die and after i start it...

A little update: Drove my car and it started to misfire badly, wiggled cps wiring and it died. Sooo, I'll fix that asap.

And one more thing. The vf is set in steps, so my first step is 0,9v, BUT sometime i see 0,5v and voltage shifts 0,5-0,8v, like it is not in steps. I think that might be the problem, but i cant understand, where to look.

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...
