Hello all,

I have the 5120 hack working a treat, but for 1 thing.

On a full tilt 3rd or 4th gear pull, the throttle plate most times closes to 40% - 50% part way through the pull.

I’m using KFLDRL to control the boost with KFLDIMX linearised.

LDRXN & LDRXNZK are set to the same max as KFMIRL.

With KFMIRL maxing at 240 and a MAF of ~220g/s its fine.

I raised the boost via KFLDRL to give a MAF of ~230g/s and the throttle plate closed to 40% - 50% part way through the pull. I raised the KFMIRL maxing at 250 and it seemed to solve the problem.

I’ve now raised the boost to give a MAF of ~245g/s and the throttle plate closes to 40% - 50% part way through the pull. I’ve raised the KFMIRL to 260 but its still closing to 40% - 50% part way through the pull.

Shall I just continue to raise the KFMIRL or is it something else?

Any suggestions most appreciated.

Also before the 5120 Hack it was working fine up to ~250g/s.

I’ve attached the a logs & the current Bin (I know all is not perfect with the logs knock etc (using UK 95 RON petrol until the tank drains down));

After pondering over the logs I think I've worked it out.

There are two problems both of which I already know about, the map is fine (need to reduce the load now though), the problems are;

- Traction control kicking-in - still got winter tyres on at the moment.
- Knock pulling the desired boost - got half a tank of cheap supermarket UK RON 95.

Sound about right?

I have no idea why he insists on doing this.
