1jz with microtech issues

[midnight_purple_GA70]

yeah i have no intentions of going flogging it as is... i understand the consequences of if its not 100% right for my car...

the -37% was from the stock twins as a setting to basically make the 550cc injectors more like 380cc injectors so that it ran better...

but was probably part of my fueling problem with the single... should be interesting to see how it all goes now but that wont be til i re-register it in december...

@midnight_purple_GA70

any update on your car?

i have a very similar setup

1jz w/ 550's and 67mm (TO4Z) turbo, big front mount, walbro pump

also my ecu has the same "steps" unlike "1jz rollas" where it goes by 5's


here are my numbers from the hand controller if anyone wants to chime in an help me,

right now i have a sligth misfire, which i think are the spark plugs, so im going to change those out

also i got my idle to be 14.7-15 AFR, but as i rev it kinda leans out to 15/16, which screen should i use to add fuel

Also on my hand controller my TPS reads +99% is this normal? Or do I need to calibrate it, if so how

Any help greatly appreciated

Thanks
