Hi All, I have just had a JWT chip fitted by a local Jap Tuning firm, nothing else yet at all. They came recomended but who really knows. Anyway, it now runs so weak that it stumbles when moving off, the ECU warning light is on all the time, and this is funny, the aircon fan is on all the time, and when applying the brake lights something like a relay rattles down near the ECU too. I gave them a perfectly good car, they had to fit the chip only, and now its a mess. Actually my brother took it to them as they rent the workshop off him, I would not have taken it away, but thats another thing.

Anyone have any ideas? The chip came from this forum recently, might it be faulty? Or did the fitters cock it up? Any ideas would be great before I shout at the garage.Thanks

OK, latest instalment. car now runs smoothly, but the tickover is low, so low it can stall when you put it in drive. I am going to take it for a run and listen to it etc, get it nicely warmed through and see. I guess it could be coincidence that the tick over is low, it OK when cold. Is the chip supposed to have JWT "properly" marked on it and a serial number? Because it seems to have no number and JWT looks like it just been engraved/scratched by hand. Not implying anything Mantav8 just trying to sort everything out and get as much info as I can. Thanks again everyone.

An official JWT chip will have a printed sticky label with a hand written serial number, IIRC.

Thanks Andy, If I remember it does have a semi see through type of sticky label with a hand written JWT on it now you mention it, dont know about the serial number though, but I didnt look very hard either.

Is this Jez in 776 Buckinham ave., working with Terry and sitting roughly opposite Phil Cunningham? In the same room as Milind, Haydee, Sailesh and Manjit?

This thread is over a year old.

 

Jez has'nt been on this forum in over a year.

This is the reason I bought a whole ECU, not just the chip, just in case..lol

 

You could always get a stock ecu, try that. It gives you something safe to get back to...

Andy is your best man for the job

Yes this is Jez from autofile! Hi!

I haven't been here for a while, the only 300zx I have left is a pile of spare bulbs in the garage.
