Ahh intressting..  But my MAF is way of scale now i think im running a 4" tube now lol...   But one problem i have in tunerpro is that i cant edit the axis to for example 0.75.. It pops back to 1 ??

If you scaled only the MAF  the timing will not off, however if you've scaled the load (KHFM) then timing/fueling will need to be adjusted. I assume you have scaled KHFM so you do not hit the 12.75 load limit ? Also wouldn't lowering only the fuel table lead to the car running rich on warm up , accel/deccel  enrichment and so on ?  Years ago a friend of mine had his car (1.8t agu) mapped like this and in the mornings it was overly rich.

RPM axis is defined as EPROM SUBTRACT so modifying one value will change the values before it. Now it's interesting how the ECU reads the value, if it calculates it the some way as define than all you would need to do is to modify the value you want and the ones after it to match the rpm you want. Say you want to modify the last rpm value from 6520 to 7000, you set 5D to 51 and than the value before it from 0D (now 6480) to 19 (now 6000) which returns all the previous rpms to the factory values, at least in the representation in winols, now I have not tested to see if it'll actually change them accordingly when running the car.

P.S. EPROM subtract for 8bit is calculated ->  (256 - value), so for RPM axis - (256-93) * 40 = 6520 , next value is - (256-93-13) * 40 = 6000 and so on ....

Hello Jim_Coupe,

I'm currently trying to tune 06A906018CJ, it is a m3.8.3 ECU with TD05-16G mitsubishi turbo.
I have dialed in the injectors 850cc siemens deka using wideband O2, scaled the maf but my current problem is the engine load.
I don't know why but my max load is 4ms and not more, regardless of MAF readings. My maf reads around 260mg/s at 1.7 bar.
Could you please tell how did you dialed the 1300cc injectors and had load that make sense?

Hi Kompiesto,

Thank you for your reply.
What I have done is I the following:

1. changed grundanpassungsfactor (FGATO) and TVUB according to my injectors(SIEMENS DEKA 850cc) measuring AFR with wideband O2.
2. Scaled maf according to housing

The result is idle load apprx. 0.45 ms, WOT load 4 ms.
I have not touched KHFM. My MAF readings are not underscaled, So I don't understand why the load is low.
Could you please explain more in detail?

Thank you
