Motor swaps and ECU's

I'm about to do a 5 speed conversion and motor swap on a 5th gen (I own a 4th, its someone else's that I'm working on). Its the stock H22A4 and we're putting in an H22A.

To keep the explanation simple, I ordered a p13 from somebody, but they ended up sending me a p28 that "needs a reflash", but came out of a 5th gen prelude. Does this mean that its going to need to be tuned to match the new motor? If so, what does that cost?

Or would it be better to swap the resistors in the automatic's ECU?

Just call a tuner somewhere near by you, and they should be able to hook it up with a base map. Normally most guys will do a base map for cheap. i know the guy that did my tune the first time, did a base map for me for like 30 bucks.

Re: Motor swaps and ECU's

Okay thanks. I was afraid of getting into the 250 dollar deals that some guys get into with tuning.

Now mind you that is just a base map. And depending on your mods, it should be close, but won't be perfect. Really you'll still need to have it actually tuned to get the most out of it.

lol its enough of a task just getting the motor undone. But I'd probably be willing to come and help at least. I can't promise too much. I'm gonna take good notes of it all.
