ITB Tuning

[topfuelman]

Has anyone had experience with or know of someone who is running a successful Individual Throttle Bodies (8 of them), Mafless, SD tune on a Gen III PCM.

Any tips or contacts would be very much appreciated!

I think the challenge with ITB's is there is no MAP sensor... so you can't run SD;

You have to run n-Alpha (TPS vs RPM VE table), which is what COS5 provides.

Actually, in the manifold design that I have, there is provision for a map sensor, (a limited volume common plenum) and factory map sensor is wired up and in place. There is however no maf sensor.
I understand that the vacuum signal is not as strong as a standard manifold, and that it is somewhat of a challenge to tune these properly. That is why I am looking for someone with knowledge or success in this area, using SD tuning.

Thanks,
