JRSC-R, engine management/pulley questions

[bigdanKG004]

Hey all. Forgive the lack of an intro, Weltall knows me.

Anyway, I have the JRSC race kit with the Hondata reflashed ECU and RC440 cc injectors. I bought the 3.8" pulley for it a while back, and wanted to know if anybody was running the 3.8" pulley on that reflash, without changing the tune on it, without problems. Money will be tight, I don't want to reflash it again or get Kpro, I am getting out of the usmc soon and don't want to spend the money but want the extra bit of boost. Please don't soapbox me, I know it's not the right way to do it, but will it work?

well #1 they dont make another reflash, you would have to buy k-pro and get it tuned

i have heard of a couple people running it without tuning but

It would still be the same tune but the engine will get hotter faster.
That may lead to some knocking problems.
If you can eventually get kpro, that would help but for now, it should be ok.

[bigdanKG004]

appreciate the feedback. i think it put my mind at ease enough to throw the pulley on, and cruise it until Kpro can be a reality for this guy.

there should be enough fuel because the reflash is going to run safe. might get a slight bit of knocking from the extra heat and the timing being advanced for the 4" pulley, but it shouldn't be a big deal.

i say get kpro and be done with it

hmmmm, i was wondering the same thing, if i can switch mine out. But i have Kpro, and full throttle with the 4.0 im peaking 5.5-6psi and my afr's are 10.9 to 11.2 full throttle lol a wee rich
