chipped ecu with zex

[shanman]

i'm currently running a skunk2 chipped jdm p13 with a zex 55 shot(h22a)- i was just wondering for u guys with nitrous what you thought of running chipped ecu's- and the throught of the advancement of the fuel/timing curves and what kind of reaction it does with the nitrous. is it ok 2 tha chipped ecu with no2? I was just courious and wanted some feedback.

thanx

There's no suck thing as a Skunk2 JDM P13. Skunk2 never wrote any code for the JDM P13. They only specialized in the USDM P13.

If you do have a chipped JDM P13 then I wouldn't worry about running N20 with it because none of the off the shelf JDM programs (Spoon, KS-Rom) advance timing or adjust fuel. They just remove the speed limiter and change the Vtec crossover and rev limit.

Generally speaking though when running a chipped ECU that modifies timing with N20 you have to know how much more timing is be put in so you can take out enough.

With a 55 shot though you have nothing to worry about, you don't need to make any timing adjustments. Running a colder plug would be a good idea.

i am running a zex 55 dry shot on my f22b1 with a chipped p0a ecu and it works fine only thing i don't like is how early vtec kicks in. i haven't noticed any timing changes.

awesome thanx for tha feedback geys I bought this chipped ecu off of egay, i'll have 2 look up and see exactly what program i'm running....i'm trying 2 learn more about ecu/different chips combo's.

rite now i'm looking into getting tha RPT Program 4 a P28 ECU.

already got colder plugs

i wanna chip my ecu but i dont kno what route to take, running a 65 shot right now

any suggestions?

thanks

if you are running a 65 shot how far did you retard the timing and is it still stock internals? i would like to run a 65 shot but i don't know.

have all bolt ons, and a 272 cam.

runs fine, i just want to get some tuning to the ecu also, but dont kno what route to go.

i have an extra f22a6 that im gona rebuild/build to handle 10-12 pounds for turbo and a small shot, 55-65 range.

thats my next project

ran into a guy named stephen that has a turbo ls engine in his civic and he runs his own chipped ecu. He told me he can chip an ecu for me easily for $50 so i may just have to sell my a6 ecu and the safc now. It'll hold off the project a little longer most likely but aem fpr, walbro 255, dsm 450's, and a chipped p72 would be a great fuel setup and wouldnt advance my timing...hopefully it'll work out for me
