2.4 TB wiring mods

Won't that cause the map sensor to read an incorrect value? i.e. it is expecting those spikes in vacuum?

vocky

the value will be the same just smoother, it's worth a shot

I not sure if you remember but courtenay did a similar thing to NickB's sc conversion

Dosent work I'm affraid, I tried that way back before the courtney RR. I plugged the original map sensor hole with the spare sensor that came with the manifold, then connected the live map sensor into the end of the vacume takeoff pipe about 2.5 feet from the manifold. Still had P1415. I tryed it with the vac pipe directly and only to the map sensor and also with it T'd in to the rest of the system i.e. with the break servo also inline. Still didnt work 🙁

That's a shame as it does sound like a plausible solution to slightly dampen the readings.

Vocky, do you reckon it's worth getting TMS to return my existing Stage II+ map to standard in the absence of the new manifold and system?

Courtenays are just starting to put the car back together now so getting nervous about the drive home in heavier traffic. 🙁

...as i already reported; Tuner http://www.trifectaperformance.com/default.aspx adapted the 2.4 TB. Don't know how they do it. Here is the thread http://www.cobaltss.net/forums/showthread.php?t=110923

Greetings cheers..

might be worth a shot, or they might be able to use the 2.4 map they have for standard injectors notsure.gif

Looks like they've made it work 😃 So I've got back to them now. Do you think they'll share how they did it?

...i mean, not to privat persons. maybe the tuners can share their knowledge.

to send the ecu to far far USA is quite hard and i dont know if the ecu is the same like in american z22se??

Finally managed to get a few minutes with Jon @ Courtenays tonight, before I left - damn but those guys are busy. I may have a possible solution to my Limp mode woes. Courtenays have obviously run into my P1514 problem before fitting the SC throttle body onto some of their SC conversions. Their solution is along the above lines of "dampening" the readings by relocating the map sensor onto an additional piece of tubing but in addition to this they've also fitted what amounts to a bush underneath the map sensor to try and minimise the spikes. It's a tiny cylinder of brass about 5mm long with a 0.8mm hole all the way through the centre of it.

If I can find the necessary bits and pieces this weekend, I'll have a go at fitting it to see if it resolves the problem (which I had 9 times on the way back from North Walsham tonight :evil: )

It also sounds like they are making progress with some additional mapping parameters for our ECU's, which could be good news for the future.

Just got back from a week away expecting everyone to be driving around with their fully functioning 2.4 tb but it seems they still won't play. I'm now considering porting my 2.2 and sticking with that. I've not driven it for properly for four months and i'm beginning to sulk 😉
