I was just wondering if anyone else has had a GQ-4X programmer work fine for years & then all of a sudden while in use it drop out of sync with PC & then USB not get recognised when plugging into ANY pc? I had one given to me that was working fine, then suddenly stopped working / being dete...

Yeah egr's on manuals are usually blocked with a plate. I've not ever seen differences in the 6 or V8 egr.s as in, no spring tension or dimension difference. As far as carby choice for this motor, my personal main deciding factor in this circumstance is lobe separation of the camshaft. Red holden 25...

After reading the entire thread, I'm curious as to what cylinder pressure a comp test gauge shows, starting with the first sweep and the total, spark cut and throttle held open of course.

Still experimenting with the eoit settings, along with the 2 extra 16 bit blocks after the boundary block. Not tried the settings on a roller yet, though the 2 extra blocks after the boundary definitely feels as though it's also further affected part and wide open throttle for the better. STD settin...

It's a dirt drag bike, the owner says if he hooks it up on a well compacted trail of dirt, he reaches speeds of anything from 108 to 120 mph over the 1/8th, assisted with a 200 shot of giggle gas as well.

Thanks again for the informative video. You mentioned in this video, the 2 x 16 bit entries after the boundary entry, I noticed those too after adding the boundary entry in the xdf I started writing at the start of this thread, I noticed the hexadecimal code itself was the same as the final full tem...

This one below wasn't a challenge to tune, though definitely unique.


Getting a lot of multiple carb jobs too!

Seems to shift it's timing as much with throttle position as does with temp change, I'm surprised I actually felt the improvement I did with the small changes I'd made.
Thanks for the demo, really appreciate it.

Seems the fix for this was easier than I'd imagined. The telematics module in the left hand side quarter panel simply needed the main plug pulled and pin 12 bridged to 25 in the plug that pulls out of it to allow the fuel pump to run. If you look inside the area in the telematics module where the pl...

Informative video, thanks, I'm surprised at how large the scale of crank timing ended up being with the temperature change, way larger than I would have thought. I'm keen to see what the crank angle / timing ends up being when changing the EOIT 4 hex bytes at a time. Thanks heaps for this. One thing...
