Just thinking about an ECU remap

<< < (5/26) > >>

rashg60:
Thanks for sharing your thoughts flashp - very interesting.

We all think that our choice of mods are the best, regardless of how we choose to have them fitted (either professionally or cheaply). I'm always hesitant when buying a car if it has been modified - the boy racer label does not disappear so easily and you always assume the car has been thrashed/abused. I suspect many of the people that have voted believe the same.

I agree that sensible mods, which have been professional fitted add value to the car and the spec. But this cannot be easily distinguished.

Another question I'd like to pose to all readers:

If you have bought a pre-modified car, what did you look for? Engine mods or cosmetic mods?

rashg60:
A month into my remap and after driving the car this weekend it all seems to have gone kerput. The power has all gone and it feels slower than stock.

I have not disconnected the battery, nor has it been to any garage for anything. I've only covered about 200 miles in it and that's it.

I will contact R-Tech on Monday but in the meantime I thought I'd try you guys and see if anyone knows what has caused this. Has anyone else experienced this?

AJP:
That's a bit crap to hear!

What was the condition of your diverter valve when you got the remap? I'm assuming they checked the dv, pcv etc before the map.

Bear in mind the remap will have increased the boost pressure, so any weak links in the chain can fail sooner than on a standard car.

Could be a boost leak, could be something else. No real way of finding out on here, so fingers crossed they can diagnose and address the issue at R Tech.

Update us when you can. And good luck.

rashg60:
They checked the DV and PCV pre-map and gave thumbs up for both - saying they were both in excellent condition.

Like I say I've just covered 200 miles in it and have not thrashed it at all.

I just feely deeply disappointed as it may mean another trip down to R-Tech.

Not a happy chappie at the moment.

flashp:
I'm sure it's unrelated. Unfortunately cars can be like this...a pain in the back side.
Sounds like something didn't like the new stress levels, engine mods can weed out the weaknesses. At least you know the engines take it well once settled.
Hope you haven't got a ridiculously long journey to make.
