So, I need to get a decent map in my prelude. its a 97 with the h23aVTEC blue top in it. Pretty much stock to the bone. Currently running on my original ECU, which engages VTEC late and has a higher redline thatn the h23a.

Question is this, who would you guys recommend to get a decent base map for the h23 from?

I realize that there is no such thing as a good basemap, but given that its completely stock, someone should be able to take a h22 map, drop the RPM's and get some numbers in there that will work. It would take a little know how though, so how knows how?

 

That is what tuners are for. Just go to your local tuner and pay to have them tune...

For a base map they should not charge much, maybe something like $25-$40 varies.
