Well Iīve been tuning the engine and so slowly,
just installed the filter right behind the lights and took it out for tuning,

Itīs most definitly sucking in colder air as I needed even more timing at high load just to make it rev,
Iīm in the mid 30īs now at the higher loads, and low 40 to high 30īs with thelighter load, I will have to remap it when the air temp sensor is put in,
as I want the 0 change to be around 15-20°C , but now itīs close to 0-5°C
and thus the need for the advanced timing,
Anyway, All the time I was doing accelaration runs I could feel the power coming on and then the soft revlimit kicked in at 6300rpm, while the power was still coming on and strongly I might add, so I bumped the rev limit to 7k and it feels alot better revving this high,

I still need to do the intake air temp sensor, but since itīs always cold out still itīs not a big concern yet,

So itīs coming along nicely, I need to get out for a while to do the fuel real good, get it straight and good before I venture into advancing the timing any more,
What strikes me odd is that in 1st gear it feels like it needs more timing then at higher gears, i.e itīs stopping a little bit revving , but that might also be the accel enrichment not beeing enough, Iīll just keep working on it until itīs all good,

Oh and guys, post your maps in the map thread,

Itīs finally behaving well in 1st and 2nd gear,
I canīt say anything but itīs VERY nice now,
Iīm going to borrow a gtech pro rr tomorrow and do some runs with it, also Iīm hoping on a 200km trip so Iīll get some very good AFR tuning time along the way, wich will even further improve the car,

Whatīs funny is that it wouldnīt work very well with map vs. rpm .
Iīm seeing 0pressure at the 3 last rows but they all flow diffrent amounts of air, the map vs. rpm would not pick that up.
