hey guys,
I really don't know much about ecu's and what not and just wanted to ask what you guys would recommend for a basemap for a 99 auto lude?

 

the stock basemap for a 99 AUTO prelude....

 

I'm assuming you're using an adapter harness because you've got a P28. If that is the case, bring the adapter harness and P28 to a tuner, and get them to tune it. No matter what, you'll need to get the P28 chipped obviously. Basemaps are really only for a starting point for tuning, or to get you (with gentle driving) to a tuner shop. If you have an adapter harness and P28, and you have the stock ECU for that car, just use the stock ECU to get to the tuner.
