Setting High TPS Threshold For Initial Tuning..NOT!!

Post by 69 1/2 Six Pack Bee »

In the manual it says:
One way to do this is to get the VE table set up by setting the TPSdot threshold setting very high (250 kpa/sec or 250 %/s, something like that) so that TPS enrich/enlean never kicks in. Then, (in steady state) set up VE table.
Yet if I try to put anything higher that 25.0 ms in the TPS thresh box it will not take it. For example, if I put in 200 burn it and then retrieve it it will come back as 1.4!! Each and every time I try to put in a nuber higher that 25 it will return a number other than what I tried.

Is this normal?
Thanx,

I think the maximum mine will allow is like 49 mv/s or something like that. It will definitely allow a higher number than you'd ever reach. I'm no software guy, and I only mess with the most basic features of MegaTune, so I have no idea why yours would be different.

The only thing I could suggest would be to try turning gammaE completely off to disable all enrichments.
