(T) JTD/MJET - induction and remaps, please read!

Could the reason be too much power, Has anyone remapped to a slightly lesser bhp to see if that works. Also would a induction kit be of any use on a standard jtd.

But this happens fairly regularly on non mapped engines ? Just less likely to hear about it.

Mine was rolling roaded pre-GSR kit, then with GSR kit and then with GSR kit and remap. The induction kit alone was worth a couple of BHP but a much more dramatic raise in torque

Everything that feeds the ECU information relevant to the running of the engine is, in theory at least, a possible 'target' for playing around with although it would be fair to say that the MAF is, in form or another, most likely the chief culprit

just something to add maybe relevant may not I have a Marea JTD 110 and a tuning chip which is adjustable if the screw is turned too far the engine light will come on so its set at its limit

Does your jtd sound nicer, ie turbo whistle and does it get rid of the air box and all that trunking. I am very very tempted to buy one and then maybe get it remapped. Cos i am thinking maybe getting a straight through exhuast at some point too. If you can get them.

It's all there, including some video (with sound) on the rollers at Red Dot

Hmmmmmmmmmm might have too now!!!! So how much quicker in real life is it over standard.
Nice stilo too.

OK, so first part of my plan has gone surprisingly well - which means it's bound to go t*ts up

I removed the MAF sensor from its housing in the GSR kit last night and 'plugged' the gap (wine cork as it happens ) but left it connected then bunged it into it's old housing and chucked some layers of gauze over the 'induction' end of the pipe (ie - the one I pointed forwards) to disturb the airflow over the sensor.

The old MAF pipe with sensor back in it was then loosely fixed "out of the way".

No engine faults on the way into work this morning - no matter how I tried to make them happen......... the return trip this evening could be interesting.

Could it really be that simple

Somehow I doubt it

In protest at being up for sale my Stilo gave me a warning light today. At idle again on pops the light and the dreaded beep beep. P0235.

It's in at the dealers for what I sincerely hope is the last time (for me anyway)

Well they just called to say they can't find a fault. They said that they can see a fault registered in the ECU which shows air-con low message and this may be the problem.

They said that only once did they see a fault like mine (P0235 at idle) and that car too had underperforming air-con. Once it was regassed it never occure again??

I remember their being a technical note / fix from Fiat about this low aircon warning problem. It does not just happen to remapped cars.

I am not convinced re-mapping has anything to do with these errors. Like I said, these happened to me pre & post the remap. Unless somebody can convince me of course.

Exactly - nowt to do with it..... had enough wee 'tickles' pre-remap to know the difference!!

Just got back and all is well. Can't believe how cold the car is now the aircon has been re-gassed. Got talking to a MW owner whose car was in for engine light. He didn't know what a remap was so couldn't get any info from him.

However the tech did seem quite knowledgeable and refused to swap any sensors or put he blame on anything particular until he was certain he had found the fault. Things might be looking up for this dealer.
