I currently have hondata s300 that was tuned on my d15b vtec turbo setup. I pulled the motor and now have a b20vtec that I am about to turbo using the same turbo and same injectors. My question is can I use the hondata map on my current setup to get around? It will not go above 3500rpm. Can i do this safely while waiting to go to the dyno?

 

If you have a wideband in the car and do not boost it, but it will still need fuel added to run correctly

Different motors have different properties

 

If you have an s300 and the usb cable, richen up the map at the Very least and keep an eye on th a\f ratio better to have it rich than lean.

 

so the map would not run safely under 3500rpms?

 

Both engines have different fueling requirements, all you can do is toss it in and see how it works
