Is that the usual situation you're able to recreate it in?

Hi Geroge, any chance to let JB4 read above 29.4psi boost? Do you know which map sensor allow above that range?

We're looking in to higher than 3bar options but so far haven't spent enough time on it.

Will definitely be a good ideal to have it for those running hybrid beyond that level, JB4 will be much more convenient compared to logging thru Vcds.

Yes it's on the to-do list for sure!

JB4_AUDI_TTRS_5:

1) Adjusted map5 to target up to 7.5psi over stock, for those running E30 or unleaded race gas who want to push things a bit. Results in around 22psi in most situations.
2) Adjusted shift boost reduction logic to further reduce boost spikes during shifts. Default setting is shift reduction = 50. A higher value will reduce boost more during shifts and a lower value less.
3) Minor adjustments to boost ramp in to improve operation under boost limiting/loss of traction situations.
4) Added support for low fuel pressure hardwire connection to monitor and rescale, allowing some fuel trim reduction in heavy E85 mixtures. Requires harness addition so is just under testing for specific cars for now.

Does this help with the 'zero boost' condition at all?

I'm testing out a low fuel pressure bias to see if we can use that to further improve fuel trims on E85 mixtures. So far it's helping, but not a lot. Maybe giving is 10% more fuel trim range on a 25% offset.

Couple logs from last nights testing which I'm running more E85 than normal to push the boundaries a bit. It's around E50, maybe a bit more.

The new additive map5 vs. an absolute map6 targeting 22psi. Both maps ran around 10.99@126mph. Hope to get some good logs this weekend at No Fly Zone, although the car is limited to 155mph from the factory. =/

I don't expect so, but you never know. I'm not able to recreate that on our TTRS at least not easily so still hunting around.

I can't recreate it easily either. When it does happen I am usually at light throttle. When I roll onto it, there is randomly no boost. I can feel when the car doesn't want to go. I would let up, stab the pedal and still nothing...
I'm not sure but it seems like certain pedal transitions will trigger this?

Think you can try to log it when it happens if you can try and trigger it?

FWIW - I've been able to log it in map 1-8 and sent it to George. If you'd like to take a look yourself, send me your email address and I'll forward over the logs.

The lower maps seem to have less impact - I can reproduce on map 4 or 5 almost instantly. I've been running map 0 for about a week and a half and have only had it reproduce once - It also corrected itself without requiring the ignition to be cut after one or two pulls.

No reported issues. I am not sure if we have done a Eurospec one yet but based on other models we cover that have the new emissions equipment no product adaption was needed.

Is development continuing on supporting more than e30? Can we get some E50 going? Are the port injectors going to get controlled eventually?

We're testing out a low fuel pressure intercept that allows a little wider range on the fuel control, no issues with E40 using that technique so far.

Ahh nice work, I wasn't sure if that was working to our benefit.
