how many of you have one fitted is it on a uk or import mods ect
has people had a lot of probs with them i have one on uk car with induction kit centre pipe and backbox been on car for 2 years just wondered as people keep slagging them off

There are dozens of posts on this issue if you use the search facility.

There are three issues on a UK car.

1. You have no overboost fuel cut at all. If you don't back off in time if you had serious overboost your turbo will probably destroy itself in seconds and very possibly take your engine with it.

2. Up to about 16-17 PSI they seem to be OK. After that some cars will det depending on octane, intake, exhaust, temperature and usage.

3. You can achieve the same as a Superchip by adjusting the actuator (screwdriver and 10mm spanner required) and using a 6 pence zener diode soldered near the ECU. Alternatively various pneumatic solutions - all equally dodgy and crude. I could do this to a car (heaven forbid) and you would not know any difference from the Superchip.

On imports there are far more issues. Do a search.

If you really want a fuel cut defender, the HKS fuel cut defender at £100 with actuator adjustments would do the same, but leave you with a new raised fuel cut, as would the under £5 circuits that I and others posted on here over a year ago.

thanks i had one on the car when i got it it was fitted by a pro
but all i have read on here got me thinking but it has run ok for the two year i have had the car

cheers john

Fitted by a Pro makes very little difference - the only thing they have to do is stop if fuel cutting (it either does or doesn't) and then adjust the defend voltage and bleed valve to get a boost level. You'd have to be a twerp to get it wrong.

The actual boost level does make a difference - see the other thread where Mark's car is IMHO running dangerously lean. If you run them at 16-17 PSI on high octane fuel with a decat and always be ready to back off if it goes higher then that makes it safer.

i asked the place where it was done and asked if it could be taken off he said have i got the key do you know what they mean is that so they can put it back to how it was

You just remove it. No special codes required. It is physically removed.

is there a safe way to keep it on what should i do or get

thanks

Get a knocklink and make sure you have and watch a boost gauge.

thanks
