Im trying to get the car to idle for now on its own. I have to keep my foot on the gas in order for it to idle. I dont have an ISC, I had removed it. I got rid of the whole system, coolant lines and all. As of right now i have a wally 255 with stock wiring but will get it rewired soon before I take it out for a test spin.
 
without an ICS you will need to adjust the biss to allow the for the additional airflow that the ICS was designed for. You need a wideband before you can tune correctly. if you have low-z peak and hold 1250 injectors, then you will have rough idle without an injector driver.
 
I have an AEM and was recalibrated last week and I'll have to double check but I'm pretty sure I bought low Inj. So correct me if I'm wrong but I thought you needed the resistor pack only if you use hi Z injectors.

I'll double check what onjectors I got when I get home later today.
 
Try changing global deadtime to 565 and see how fuel trim reacts. Right now the car is adding 12.7% through the fuel trim and you want it to be <6%.
 
Well looks like I do have low z injectors. So I will order the resistor pack soon and then give the global dead time a try and then post another log.
 
those injectors are peak and hold. you need a resistor pack but you shouldn't have to order one. you already have one on you car and those injectors look like a direct replacement so just install them and plug em in.

Never mind I'm confusing myself here. I have a resistor pack installed and was thinking I need the delete plug. Tomorrow I will get a new log and and move the dead times around.
 
did your injectors not come with a dead time spec sheet? when i bought a set of ID1000s for my rsx, they came with one.
If you didn't get one you may wanna check to see if one is available for your injectors.

Alright so I pulled a new log today. I bumped my dead time up to 615 and got the fuel trim down to <6. But I noticed as I got done that my gas pedal sticks and it was on 2% throttle. Ill have to lube that up and redo the TPS adjust. But as I got done I also noticed that my alternator isn't charging. I have a brand new battery and I just put on a brand new alternator last week. Ill have to look into that too.

Got a new log done. Alternator seems to be fine today and gas cable lubed up. Got my Air flow per rev down to .30 ish but cant seem to get it any lower with out stalling the car. Got my fuel trims down as well. Doesn't idle the greatest yet but its getting there. Any suggestions?
