Hi Guys

Hope this e-mail finds you well.

Tuners help K-PRO.

My car is eqiupped with a F20C K24 Conversion with 12:1 CR. At last i have managed to buy and install jenvey ITB's. I have a problem with the calibration . problem is that the car will start but stall immediately . Obviously cannot get a reading from my Wideband as it is not giving me a chance . I m working on Alpha-N and using vacuum source direct from the vacuum booster into the Map sensor. i have calibrated the TPS against the K-Pro and it is reading 2.7 on low and 97.8 on WOT.

Do i have to calibrate something else before start trying to tune ??

Problem is that i live in Malta and there is not enough tuners here who experienced setting an S2000 with ITB's.

Or if possible maybe somebody can send me a base map to start with ? My e-mail address is nicknat6@maltanet.net

I will be than great full for your help.

Thanks in advance
Nicky

 

Any Help please ??

Thanks

 

This is a "stock" ignition map.. see how it has a steady decrease in ign timing as load goes up



This is what you'd see with ITBs. fairly flat then a "steep" drop in timing. This is because map pressure at partial throttle is much closer to atmospheric than with a typical manifold.
