problem <U></U>
when we put the kit on and started up the car the car would start but was running really lean and would cut off after stayin on for about 20 sec. If i would give it gas the rpm won't even move it will jus stay idle and then cut off. after unplugging the map sensor the car would idel fine but would be running really rich and is drivable but only up to 2k rpm. i know i have to get it tune in order for it to run right but does anyone know why it won't stay on and running so lean when the map sensor is plug in, and also why i can only go up to 2k rpm when the map sensor is unplug?

I would say wrong baseline. You said you burned it for 1 bar? Isn't that for N/A applications?

FredoSP

dont you need a resistor box with those DSM 450cc's?

boostedcivicsir

hondata will not idle DSM injectors properly. i tried 680's with a resistor box and i had the same issues. i now have RC 650's and have no idle issues.

from hondata's forums.

"DSM 450cc injectors will not work with the Honda ECU - the electrical characteristics of the injector are not suited to the ECU, resistor box or no resistor box.

If you use DSM 450cc injectors you will find the engine difficult to start, and the engine running lean at part thottle, plus tuning is very difficult."

sounds like it's just too lean. add fuel in low vac and low rpm to get started.

PM-Performance

how can you assume its too lean without a wideband? how do you know its not too rich?

Again DSM injectors wont work with Hondata correctly.

thanks for all the feedback everyone. imma try to get some rc 550 and see if that will make a difference and also went and got a resisstor box off a 94 accord. i did use resistors for the dsm but they were those cheap radio shack that are like 10 oms i think.

Cyphear

those should work.

everyone else is probably right, but this came to mind

are you sure you plugged the map sensor and tps in the right spots.... these are swapped alot... it causeing the car to run like poop

try swapping them, cause they are the same looking connector.... see what happens

numba1 si

thanks ill try that tomorrow

numba1 si

the map sensor is plug in the right place and still having probllems

Mr.DC2TurBo

are u running a 3 bar map sensor?

Cyphear

sounds like your basemap is really rich or lean. get a better basemap or hook it up to a wideband to see if thats the problem.

pornstarSR

yep well now that you made sure the map was in the right place.... tunning

basemap is what it seems to be

boostedcivicsir

i still think it is the dsm injectors.
hondata says they will not work without a lot of effort and a basemap will not idle dsm's properly. period. i have been down this road, failed, and the 650's rc's i have now, idle flawlessly, and do not stall the car out. the 680's from extreme psi i had, would not idle the car w/o 70 psi rail pressure, stalled the car constantly, and was so damn lean at idle the car wouldnt hold an idle. i agree that after a base map the car needs tuning, but if he is running dsm injectors, he will be chasing his tail. so far hondata's basemapwizzard, has been right on to get a car to idle. we havent had any issues with the map wizzard. i am not saying it is perfect, but the cars we have tuned had atleast idled with no issues except mine with the dsm injectors.

Mr.DC2TurBo

With the only information u gave us, I would assume u are NOT running a 3 bar map sensor. You have a hondata that is set to 1 bar. Therefore, U need a GM 3 bar map sensor for everything to work correctly You can't run stock map sensor when your hondata is programed to read something different.

1SLOWREX

THE DSM INJECTORS SHOULD WORK CAUSE ME AND MY BUDDIE BOTH HAVE THEM AND I HAVE A RESISTER BOX ALSO. BUT WITH THAT SET UP UBERDATA SHOULD WORK FINE BUT NOT HONDATA

numba1 si

well ed that work for balance performance in ga burn the 3 bar for me befor and it was acting jus like it is now. i told him i only wanted to run 7lbs and he told me just to use a 1 bar and thats wut he burn for me and that is whats int eh p28. The hondata is not plug in, just the p28 that chipped for hondata.

numba1 si

1slowrex i don't get what your saying? your telling me that the dsm should work cause it work for your car, but then you tell me it won't work cause i have hondata???

Mr.DC2TurBo

i think u can't just run the p28 without the hondata. You need both item in the car unless u have s100 where hondata is a chip in the ecu.

numba1 si

im not expecting full boost. i jus want to be able to get it to the place im tryin to get it tune at. im just wondering why the car won't go up pass 2k rpm and why it won't stay on or rev at all with the map sensor pluged in.

with which map sensor plugged in, the 3 bar? or the stock one?

did you try to plug in the stock one and see if it would run better, if the chip isnt burned how you think and the ecu is looking for a stock range map it will cause it to run baddd...

just an idea
