Hi Terry
If it's one or more of the Mosfets, shouldn't there be a short circuit somewhere at the bad Mosfet then?
I've bipped all twice and no short circuits at all on any of them.


Best regards

You sound quiet confident about it's the Mosfets, Terry.

But shouldn't there be a short circuit on either of the 2 legs to the other side on a Mosfet then or can't you really count on that?
Cause I've bipped them all out twice and no short circuits anywhere?


Best regards

After second thoughts and looking through pictures it actually also had these alarm codes:

-DME active codes-

29F1 - DME: Fuel pressure, plausibility.
2A2B - DME: Mixture control.
2AAE - DME: Fuel pump.
30BA - DME: Injectors 1, 2, 3 or DME, internal fault.

You need to resolve 30BA first...as stated that is mosfets. Until you do that, there's nothing else we can do for you.

Ok Steve, thanx for confirming that when it’s the 30BA error code it has to be the Mosfets no matter what I measure.
Then I’ll also get the Precision coil upgrade and some 2-step colder spark plugs.
Hopefully all probs would be solved after that


Best regards

I'd ditch the coil "upgrade", stick with good factory coils.

Ok Steve, so your advice would actually be to get all the Mosfets replaced, 6 new spark plugs and then keep the coils there's already being used now?

What are your thoughts about trims in map 6 Steve,

is it too rough for my HPFP and would it suddently crash?

Can any adjustments somewhere make a nice move regarding the trims or is the only solution E85 (which I don't have in mind) or lowering boost for map6 in user settings?

Can you suggest anything else for improved performance?

It feels like it revs slower than it did before I updated with the
pump flash I8A0S here recently and I can also barely hear the Tial blow off now?

Really appreciate all the help I'm getting in here

Replace all your mosfets, do a log, and we'll go from there.

You are running way too lean and trims are maxed.

You can bump your FOL up to 90 but I think you're beyond that.

You also have a bunch of weird settings...

I'd suggest putting everything back to default settings and adjust the ones for your hybrid setup.

You may need to adjust your scalar in the flash if the 100 octane fuel you are running is maxing out your trims like that.

I'm finally about to be getting all 6 mosfets changed this weekend, so happy days..
How to go from there, do the Mosfets need to be programmed in any way?
Do I need to upload the BMS flash again through MHD or is there nothing I need to do except for putting in the DME again and then hit the start button and hope for the best?

Xtra question:
Should the resistance in the old working mosfets and the new mosfets be exactly the same?

No, the Mosfets do not to be programmed. Nothing else you have to do, just like you said, hit the start button and hope for the best.
