Tuning the VTEC maps - Innovate/PR3/Stage 4

7rrivera7 · Post by **7rrivera7** » Sun Jun 13, 2004 7:41 am

I've finally gotten a good low cam fuel tune using my Innovate wideband and I'm now tuning the hi map. The problem is that my Stage 4 will not display the recorded lambda values on the hi map. It puts everything on the low map even though I'm in VTEC from 3-9k.

I'm tuning the map by eye looking at the low rpms and converting for hi rpms but why does the hondata record lambda only on the low table?

I hope I explained this clearly!

Since your using OBD0 it does not show the vtec crossover. This is why Hondata recommends upgrading to OBD1.

Thanks, I didn't know this was 'another feature' we ODB0 guys are missing out on
