FYI I have a 62-2 trim ct26, 550/lex, and running 19psi. No fuelcuts at that level.

Beals;1931438 said:yeah but stock turbos don;t pull hard after 5500 rpm, even if the ct26 pulls hard to 6k it's gunna start leveling off, this is when AFPR and wideband o2 sensor is a good idea to monitor, it's also an easy 500$+ combo.. the other route is an SAFCII and get someone to tune into a safe range for you. I wouldn't run over 16 on my 440's(1jz) personally even though I know with cams and my aftermarket ecu I can push 18 without fuelcut, but I'd be worried about it going lean somewhere close to the 7k rpm mark.
Nick M;1931496 said:Saying you have no tune sounds quite dumb. If you had no tune, the car wouldn't run. You have the Toyota tune.

Anywho, people calm down, get off your high horse and just try to help a fellow poopra owner out.
thevork;1931842 said:^IIRC you can't use an SAFC to "make your Vf signal happy" because it's only functional in closed loop. A piggyback will only help you get better A/F ratios in open loop.
The best way to "configure" the closed loop with the lexriemer mod (in addition to the adjustment screw) is a 1:1 AFPR to set the base pressure to whatever your specific configuration needs in order to make the TCCS happy.
IndigoMKII;1931853 said:Basically what I was saying. My car runs near 2.5 VF til open loop which it then runs 11.2 AFR and slowly goes to 10.9 as the RPM's climb.
Nick M;1931905 said:It is supposed to do that. However, 10.9:1 is a little lean. I have seen the Toyota tune as rich as high 9s and low 10s.
