Hey guys, I need some help. I'm running DSM injector with a resistor box on my lsvtec setup. My car is throwing a code 43, but before that happened my car started to misfire. The misfire happens only when I get on the gas hard. It's leading me to beleive that it's my ignition coil, but could it be my resistor pack? The injectors and resistors pack has not been on the car that long.

I could go changing out everything until I find the problem, but I was hoping someone would have experience with this issue. Could it be that my ignition coil is not putting out enough spark giving me excess fuel. If anybody has any idea, please share. Anything information is better than nothing right now. Please help. Thanks.

code 43 is for fuel supply system.... if you have an obd1 ecu we can chip /tune your ecu and get rid of that code.

Yeah, the code is fuel malfunctioning. The thing is that I'm running the hondata s200 system. I got the motor tuned for drivability with an exhuast on. I sold the exhaust system about three weeks ago and I'm now running open header (not daily driven right now), but the code 43 just recently came on. I'm running a hytech header and the bung is close to the collector. Could the o2 sensor be reading too lean?

Whitfield-Tuned, do you have experience in the code 43 coming on because of rich or lean air/fuel mixture? What do you think it is?

Any suggestion is appreciated? Thanks.

Oh, by the way, the motor was tuned for it's drivability with the DSM injectors.

 

i personally do not like te dsm injectors however if you are on s200 then it should not throw that code

 

Bump for any other thoughts

 

Hey Whitfield-Tuned, I have the same problem right now. How much do you charge to get rid of this code and tune it on crome. I been meaning to hook with you. Scott at b-series built my motor and told me to give you a call.

 

crome has the feature to dissable the injector test circuit and yes i can tune 4 u no prob pmed

Just curious to know why you would want to disable this code. It's suppose to be letting you know that something isn't right. Are you saying that this code isn't needed if a person feels like everything is working properly? You must have had some kind of experience with this code 43 to lead you in saying that the code can be disabled.
