well, ECU fried itself loading a tune today, fuel pump and tachometer freaked out. Now ECU wont connect.. car wont start....so yeah....

here it was untuned on speed density

[Wschnitz]

That exhaust popping though.

[kamotors]

needs some tuning lol

[kamotors]

BTW its so loud I had to put the external mic in the car lol

[kamotors]

here is how throttle calibrated during its death.


:( satans chariot

[Kevinl]

looks fairly quick it must run pig rich should be a beast once it gets tuned

[iXguido]

that oversteer though :D that sounds so amazing, driving impressions?

[kamotors]

perfect balance, I love it, just need ECU fixed now and then I can drive it everywhere.


anyone have alpha N tuning tips?

car wouldnt drive on ITB mode was just stuttering

[Wh33lhop]

dear lord, that sound.

[delamaize]

Boo for fried ECU.....

Dat sound tho.......

Fix your TPS signal for one. The closed throttle count should be less than the full throttle. You are relying on that TPS signal in your maps, I have found the signals are very unstable when you have the count reversed.

To further this I believe he's pointing to the fact that you may have a pair of wires swapped on your TPS wiring.

Correct. And while people keep telling me "it works that way" it's still not correct, and it gave us problems on the ITB builds we have done. Also, the more sweep you have, the better.

To add, on the street cars we had to increase the resolution at low TPS settings. Really thinking about doing dual maps in the future. Something like map1 0-10% throttle, map 2 10-100%. Local kid came by the other day with his m42 turbo. I was impressed with how smooth the car was having dual maps for increased resolution. He has 0-100kpa in map 1, 100-200kpa in another. Wasn't until I was adjusting some drive-ability issues on the Extrudabody car that I realized how nice the dual maps would be for ITB's in a DD.
