[Mk2] [Turbo] top end

[daiodavies]

Hi I have a rev 2 tubby with uprated intercooler mongoose exhaust and blitz ecu just wondering if anyone knows why my car tops out at 130 mph as I thought the ecu de-limits the cars top end???

What do you mean by tops out? Does it hit a limiter, which is quite abrupt...or does it just run out of go?

[daiodavies]

Its quite a harsh limit but I thought the blitz ecu de limits the car?

[ashley]

I think the stock ecu limits the car to 120mph...maybe the Blitz has increased it by 10mph

Might be worth using one of the aftermarket de-limiters?

[daiodavies]

Where do I get one from? I asume its not a fuel cut defender I need??

You speedometer should have been converted when it was imported. This will also remove the 112mph JDM limit.

Remove the instrument cluster and check whether you have one soldered to the loom.

If not, on ebay about £20.

Ah- 112 not 120

My speedo is out buy 10mph so do you think it has not been converted ? but that doesn't explain why it has a harsh limit at 130 mph
