Hybrid K04 Turbo Review....

[wild willy]

I dont think changing requested values will do much tbh. If the turbos going to produce 1.2bar at 6500, it surely doesn't matter if ecu is requesting 2000mbar or 2400mbar at this rpm.

You fitted yours yet Carl?

I'm not sure about that mate, i suppose it depends on the duty cycle but i thought the ecu would need to be requesting more to get the best of the turbo.
have you logged the duty cycle recently.

and still no turbo fitted on my car yet, but i'm looking forward to it.

Nope not logged duty cycle for a while now.

Will have another play at weekend i think

 

[Mitchy]

As to requested values, yes i do agree that requested should always be above actual to get the best from the turbo. The wastegate should be working at a harder duty cycle to meet these requested values.

JBS is a 110mile 1 way trip for me, but the next time im back James is going to have another look at the map to see if it can be improved. I still need to have a fiddle with custom settings but at moment still trying to source a cable.

Nice Figs, Glad too see you've got acess to vag com. They look very similar to Mitchy's. The Hybrid is a full 0.1 bar better than the stock k04 at the Red Line.
Are you going to any RR meets this year for some updated figs.

 

[wild willy]

Do you have any Mass Air Flow logs, to compare.

 

[YerMother]

You can't compare b'cos i run a larger MAF housing with a 4 Bar FPR. Its around 185-190 g/s. But means nothing!
