Interesting Side Effect of LPG installation

Gave my Ute a flogging today, as it my last day with, trading it in tonight....

Anyway driving flat knacker, I found that the speed limiter doesn't work when running on LPG.

This will be due to the speed limiter being fuel cutout related, and the Impco LP system having its own engine manangement system.

At ***** I decided to back off before the secondary , more forceful, speed limiter activated and the tailshaft popped out.

Where do people go to speed so much? After losing my licence for speeding, I still haven't taken my AU over 130 :( I did take my old EF to 170 though on my home from Ballarat one early morning, hehe, thank god I didn't get caught that time!!

Thats interesting jesmol, i was in my mums AU fairmont running on LPG and lets just put it this way, we definately went over the limiter! it wasnt slowing down either but i told her to cut it out

For me best land speed record to test is early saturday/sunday morning at "censored" with no cars on the road and keeping 110% alert. Have driven the EF to the limiter, felt planted and very very smooth. Was awesome.
Wish the limiter wasn't there i can see 210km/h+ easy.

Oh yeah have driven a VT commodore to 180km/h, took heaps longer to get there compared to the EF. And didn't really pull as the speed over 120km/h.

Haven't driven land speed records in the XR6.

If you want a real treat, plan a trip to the Northern Territory. When you hit the border it's open slather but watch out for wandering livestock, particularly at night.

Guys, I agree with Laminge on this one, and apologise for starting this off. A little irresoponsible of me I suppose, but its an emotional day......

There is only one particular stretch of road I will do this down (and have only done this twice in two years), its a down hill section, no side roads, and at least 20m visiblity each side of the road, and 2km view up the road for oncoming traffic. Its also a well and truly out of the way area in the Adeliade Hills

I raised this more as a peculiar side effect of the LPG install, and have just had a thought about the legality of the install?

I would have thought any system that removes a speed limiter is illegal?

The reason the limiter doesn't work is it is fuel based, and built into the ECM , so when 180 is reached it cuts fuel out, gradually slowing the motor down to about 175 when the power kicks back in.

LP system tend to run their own control system which in my does have a speed sensor and therefore could not have cutout LP supply

A spark cutout could achieve the same effect but it wouldn't be able as smooth a cutout?
