Hey, I have a JWT tuned ECU for sale!!!!! it's tuned for 740cc inj and Z32 MAFS.

I ran it on my current set up which is S14 SR, 740cc inj, Z32 MAFS, 2871r .64, and HKS 256/264 cams. it made 315whp at 12psi with a good power band.

I switched to a stand alone set up so i have no more need for it.

I'm selling it for $400 O.B.O. i bought it for $650 so this is a steal!!!

either reply here or PM me for more details!!

that is the EXACT setup i will be running in my car in the spring. i have been thinking about sending my ecu out to jwt. why are you switching to standalone? what ecu code is it, and does it matter? ie, mine is a wc. anyways, i might be interested but don't they tune based on how much power you are trying to make? like, i am trying to push 18-19 psi on mine and make 350-380, would it still work without being re-tuned?

I switched to a stand alone because i thought it would be better but it really wasnt a big difference. I only made 10whp more. Cody Ace is making 400whp on the same tune with a slightly different set up.

I also switched to a stand alone because i wanted to run e85 (which is gods gift to man kind lol i pulled more tq than hp on it)

their tunes are based on what the maf reads from what i understand so the boost level doesnt matter really aslong as there isnt any detonation.

they also tune for the type of fuel you use. i have it tuned for 91oct but you can run 93 with it no problem.

I recommend that you get on a dyno and raise your boost to make sure that you and the tuner can make sure there isnt any detonation at all and you can get your hp readings there. i ran 18psi no problem until my fuel pump crapped out.

I put down 315whp at 12psi with this tune. if you want a re-tune to dial things is more then its as simple as getting a datalog readout and sending it out to them. they dont charge much for the retune.

my ECU code is NA.

I had a JWT ecu on my s13, i made 242whp with the T25 turbo at 12psi. I really loved it but also swithced to PFC due to the factory knock sensor picking up noise from my built motor and twin plate clutch.

Buuuump! I know someone out there needs a reliable tune!!!

*nissanfreak317* · 11-02-2009, 04:41 PM

it looks like the na and wc coded ecu's are different. found it here.

SR20DET WC ECU? Black? Red? Zenki Kouki?

mine is a red wc, lol old school.

anyways, can you post a pic of the side where the harness hooks up? maybe it would still work...?

thanks.
