Thread: Turbo Problems Please Help!

Its kinda hard to read but the number written on the jwt sticker on the chip is S114CFM7.T4J

I'm waiting for them to call me back to see what it is for sure tuned for.

Here are the pics of the stock and jwt ecu.

We should just double check things first to make sure its not the simple things like Tekkie said 99% of problems related to vacuum leaks and such. We could do other simple things to like regrounding maf and so on.

Hopefully we have just sprung a leak down low but if not we can move on to the next steps. Thanks for all the replies guys and we will do some work when it stops raining!

That's a stock maf 3 bar 370cc ECU, I used to have the same exact thing on my ECU If you bought it used you might wanna send it in for an upgrade, JWT is slow right now and the turn around time is less than 3 weeks, for extra you can get it overnighted. Since you already have an adjustable FPR and a Z32 maf, might as well get a 4 bar Z32 reprogram and I bet it will start right up...

I would chop off the adapter side of the maf and just put a coupler on the other side. People have trouble getting the adapters to seal properly under boost.

Also your maf is very close to the throttle body which may be causing issues as well.

You also dont need to recirculate when in draw through. Ive been driving for 3 years draw through and un-recirculated.

Lots of good tips and suggestions here from both of you. Thank You! I need to try some of this and make some decisions quick. I want to be ready for the track on May 2nd!

easy fix get your jwt programmed for a z32 maf/4bar or 3/370cc inj..or send it out to a forum member to reprogram it for you..done

who can reprogram a jwt ecu? i know jordan can send it off and get it reprogramed at jwt but that involves more time than we have before import faceoff. he came in second place one year with his all motor 200sx. he is looking forward to running in the forced induction class this year.

We were also thinking about swapping in some injectors I have for my mustang when he goes to 4 bar and top feed injectors. i have some 04 cobra 42lb injectors sitting here.

Its prolly quicker to overnight it to JWT and have them express it back to you. Call them and ask they are pretty friendly!

just talked to jordan today. looks like he is gonna send it off to jwt to get it tuned for z32 maf and 370's at 4 bar.
