Hondata

I just recently installed another ls swap into my car and boosted it. I have hondata s100 and a chiped p75 ecu. My motor is bone stock and my setup is a t3/t4 .57trim, dsm 450cc's, and 3 bar map. The s100 light is staying lite and im not throwing any codes what so ever. BUT the car wont idle with out sounding like it's about to cut off. It's idling at about 100-500 rpms and skipping. Sometime when you give the car some gas it smoothes out and somtimes it just stutters real bad. When i try and drive it down the road it barley runs and has no power and stutters. What might possibly be my problem. My ecu is tuned for my exacty setup. Could the tune possibly have gotten erased or somthing? I put in new plugs and in one day with less the a mile of driving they was solid black with carbon.

Also ive done tryed adjusting the throttle cable and idle screw...

You mentioned tuning on that exact set up. Did you mean tuning was done on the actual engine and car?

From what I understand you are using a new engine with an old tuned ROM with the same set up.

Nah a car with the exact setup. Yes im using a new engine with the old tuned Rom. Also i accidently placed my ROM chip in backwards which probly caused it too over heat or scramble so im gonna send it back to Va. to get my program reburned onto it.

Better to trade up your S100 to S300. Comes out cheap with their promo.

Is the other car using a 450cc DSM injectors also? Resistor box installed?

yepp and i have a resistor box
