Any hacked mafs updates?

Any more news on the hacked mafs working out well for some people or being the cause of detonation for your turbo application?

Mine was fine at 4.35psi and ~6psi with no intercooler...

With the intercooler it was fine for ~6psi, and even 8psi for the last 2 months. But recently, the blinky A/F gauge has begun to show a little more towards the lean side of things. I swapped in a new KA (my previous one had a blown piston from detonation [too much timing], but I replaced the piston. It still had piston slap, and was getting annoying so...) and want some reliability out of it on track event days...

I ran with the stock ECU for the last week and the speed limiter sucks...as does the lower rev limit. But the A/F looked better, and it naturally had less timig programmed in then my JWT N/A ECU...so it was safer.

Anyway, my plugs were showing a little lean after the swap...and I was already running an N/A upgrade - So I just called JWT up and have a turbo chip coming tommorrow for $100. So now I have timing control under boost and compensation for the 370cc injectors...can't complain.

Now AceInHole is the only guy running the 'Hacked MAF'...

Thanks for the info. I just read a thread Ace started and his setup was running well at his last track event so that's another plus.:D

nope :D

but i can't say anything for now as i haven't tested the car all out yet. Only did a couple of udner 3000rpm runs with the wastegate open (eg no boost). But for those runs the a/f gauge steadily gave a reading on the border of stoich and rich. And i'm using the same concept but a little different setup. I'll post sometime later when i finally get into boost and fix all the crap (like the master cylinder bs).

That was exaclty my issue. So I pulled the plugs and they told the story: White = Lean.

Not good at 8psi with lots-o-timing advance...

Keep us updated.

bump* for this thread
i'd really like to see the updates on this
im planning to run hacked mafs too

hmm weird... i pulled my plugs when i first started up the car and my plugs were white too. i blamed it on being like that before... guess i have to put some restriction in there to reduce alternative air flow and see what happens then.

My plugs are white and I have no turbo. I thought they were always going to be like that until they were out of commission.

i run N/A but mine turn red on some parts..not rust..jus red
