Hey guys!
Need help here! So while cold my A/F ratios are all over the place! and I need to fix this, It happens mostly if I drive the car cold it will even die because it goes way to lean I have to be on the throttle to keep it alive, I think my VE tables are off.
All about tuning is while the car is warm but when warm it runs ok I don't want to wait 15 minutes every time a want to go for a ride!
Also is it normal the TPS volts be at .59-.61 and as soon as I turn on the car goes to .63?
Why Idle is so bouncy? No boost/vacuum leaks
Whats the correct deatime for the RC750 injectors (mine is at 315) and how much cc they actually flow so I could input the correct global!
Everything I write about is in the log it even died while I was logging help me guys I'm on my own down here!
RC750cc
FPR at 43psi
DSMlink on SD
Spark plugs gaped at .28 bcpr6es (<--- different name for the US, same plug)

Try adjusting the CoolantTempFuelAdj direct access table. This will adjust fuel delivery based on coolant temp to make it hopefully act a bit more normal when cold. But honestly the best way is to let the car warm up a bit before driving if you can.

Also is it normal the TPS volts be at .59-.61 and as soon as I turn on the car goes to .63?

Can't say I've heard of that before, but if it's reading right at idle and WOT, I wouldn't worry about it.

Might be because it's cold?

Whatever it takes to get the idle dialed in. Most places will only give you a ballpark deadtime number and it's up to you to tune the idle and get things in check, which may required adjusting deadtime.
 
Thanks guys! What I'm trying to say about cold drive is, I really take it easy and stay away from boost and shift around 2500rpm but you never know in case of an emergencie anyway I'll try the coolant-temp values is if that helps car was running great before It just happen after the SD set up that's why I think the VE table is off
