FWIW the matter turned out to be due to alternator belt slippage and has been resolved by the simple addition of a tensioner pulley

I appreciate your help, I really do.

The P1516 disable was a last-gasp addition which made no difference. It wasn't tripping that code even before I disabled it

Gents,

The car has no physical MAF sensor installed, been running this way, with those MAF fail settings, for 4 years now. I will try setting MAF to 1/0 Hz but I very much doubt it will change...

Thanks for getting back to me, I have attached a copy of the stock file off this PCM. As you can see the OL Gain tables are untouched, and we're running a 2-bar MAP sensor so the values should be...

Hey guys,

We've been running an SD-only E40 on our drift car for years now without issue. When I swap out the LS3 intake manifold & injectors for an LS9 blower setup with 100lb injectors the car...

Not yet, delivered the car to the customer. Will definitely be doing this next time around @ the next round of mods :)

Just wanted to report back myself, putting max map @ 197kPa solved the issue and all is good now!

What's happening here is that its simply cutting out/hitting an early rev-limit, making further tuning impossibru. What I might do, if there is no other choice, is to rescale the MAP sensor and all...

Quick update for you guys. I performed all the suggested modifications to the tune and tried again. Still the same no change... It would appear as though its cuts out @ exactly 200kPA which leads me...

make the same changes to the MBT tables and you should be golden :)

What I found very unusual was that the indicated (graphical) ECT and IAT readings on the dash you see are not the same as the textual ECT & IAT values you see on the left half of the VCM Scanner....

Yeah FWIW I logged throttle torque source in a later datalog (which unfortunately I did not save) and it remained @ "Pedal" throughout, despite the early cutoff (where you can obviously see the...

Thanks a million! Yes, I do

Howdy all,

I hope you don't mind me reaching out for a helping hand, as I'm at my wit's end here. I'm in the process of tuning a cammed Procharged 6.4L SRT8 Challenger with with built motor, 3-bar...

If I did I wouldn't be bumping this thread :)

necrobump!

crickets...

Anyone? :cool:

Hey all,

I'm tuning a built turbo LE5 with an 06 E67 controller and had a few questions to ask y'all, but first a quick rundown of my setup:

Wiseco 8.x CR pistons
Carrillo rods
ZZP LE5 cams...
