Problem is as they age they become less accurate

hope it's not only age but milage that counts ?
my spares has less than 2oo'km ...

No MAF, what is this Voodoo

It’s called “speed density” instead of having a MAF the air mass is calculated from the air temperature and pressure. (MAP and IAT). You can do this with most aftermarket or PRJMod.

Yep, simplifies, and perfectly up to the job.

There a lot to be said for going for 'speed density', does a away with a ridiculously expensive component and works very well.

I picked up a new MAF from AT for around £200 about eight years ago, got the normal S2 version as opposed to the ADU which was nearly twice the price, their the same apart from the screens.

IN this log : its a cold start, spark angle is 7 degree, but value in table is 12.. strange..?! When the coolant gets warmer, things getting worse, I have no idea..

Hello! Today i measured the values of the TPS ,.. close position

Pin 4-6 - 0,2 Ohm (must be zero i read)
Pin 2-3 - 0,945 Ohm ?! (must be 750 - 1300 i read)
Pin 1-2 - 2089 Ohm (must be 1500-2600 i read)

Is this broken??
