Hello.

I have just started calibrating my 1300cc injectors on E85. As s start im using stock 2.5" MAF. The constant "Grundanpassnungsfaktor" is the faktor i belive i must change. As a start i calculated the following: 210cc/1300cc = 0.16  ...This faktor did not work at all and the engine was running very lean. I cLibrated it manually and ended up with 0.42 as faktor. This made me abit confused. I also lowered TEMIN wich  resulted in a more stable idle. Could it be a faulty TVUB thats is the ghost here? Or is there any other maps that i have missed for caalibrating these Genetsis II 1300cc injectors. I have asked the seller to send me the injector times aswell.

Now engine runs OK but i have som issues with throttle respons at idle. The engine stalls abit when pushin pedal down fast.. (I have only been testing at idle). Maybe i shall take it out for a drive to make it adapt?

Progress made. Started the engine with stock MAF,1300cc and E85. Ended up with injectorfactor 0.31.

Now in moving over to big MAF 4" in size. But ran into som starting problems. I rescaled the MAF table and managed to start it on cold engine. But as soon as it got warn it was impossible to make it start again. It fired but not enought to make it live. I suspect that is runs lean. Now the big question is where do i find cranking enrichment on m3.8.3. Hmm with a clue? Ive seen the faktor "stargrundmenge" but what does it do?

Here's a tuning map pack I made up from some good stage 1/2/3 1.8 ME3.8 tunes.

Included is the ORI and KP, hope it helps

Nice.. looks like you had some intressting maps there aswell.... Cranking fuel constant was exactly what i was looking for Smiley

You also had KFBAKL.. Didnt know m3.8.3 used that map.. I thought KFWDYN.0  was accel enrinchment in m3.8.3.  ?

81BE 6x8 in 8bit factor 40. stock value is 6800, adjust to whatever you like

NMAXF is at 76B8 in 16bit, factor 0.25. Stock is 7100 RPM.

For being a BIG ASS TURBO build car runs pretty ok now.. Smiley    Raised soft revlimit to 7200 hand hard to 7500rpm..

Now i want to shoot flames and gargle pop... I have read the offical "gargle pop" thread but i only found KFNWEGM...   But if I retard ign and raise fuel in the area when throtthle is closed that would give me some bangs right ?

ok on 1.8T that's quite big  Grin Grin
Put KFNWEGM higher as NMAX and CWSAWE to 1 and lowest lines of KFZWMN to -30.
IIRC that was enough on my car.

Johan, it is not ME7 so maybe he needs different maps.  Wink
Jim, maybe you can send Eliotroyano a message, he knows a lot about these older ecu's and he is very helpful.
Did you build the head? I think you want to rev to 9000rpm with this turbo  Grin keep us updated.
