fuel cut defender??

[ABZY]

hey all, not to long ago i heard you could put these on N.A engines, although it doesn't work as effective as on a turbo... i was wondering if this was right and what the advantages/disadvantages would be...

thanks ABZY

what do u think it will acheive?

They are designed to work on Jap cars with a speed limiter on them to stop them going over 180km/hr. They don't do anything else. I would doubt that they don't work on turbos as i know they sell them for a Supra, a friend of mine has a Jap spec one with this unit and it worked fine.

They trick the ECU that the car is only still at about 180km/hr to allow it to go faster.

that is something some of them do, however i believe thier primary objective is to allow turbocharged motors to run more boost past the stock limit of the ECU (where they introduce a fuel cut to stop overboosting). With no boost to be had on an n/a car, makes it a bit of a waste....

Yep the Speed Limit Defender is the unit the eliminates the 180km/hr speed limiter. The Fuel Cut Defender fouls the ECU and allows you to run more boost instead of using a boost controller. I would not recommend using these as you can get surge and mis-readings as opossed to a electronic boost controller which is much more reliable.
