Question Odb-II question

I have a 97 LX D16y7 manual. I'm going to install a D16y8 intake manifold and a D16y8 Throttle Body complete swap. Also a DC sport 4-2-1 header. Now I have a ODB-II ecu, I see that I cant have that modified. Is this true? If I can, what ecu is recommended? If I can't, should I just Flash my current ecu? Thanks gang

You need to do the OBD-2a to OBD-1 conversion, get a p28 ECU, and then get it chipped with Chrome/Uberdata/Hondata/Neptune to do some real tuning.

You would need to go with a Y8 head and a vtec controller to get vtec.

And no, you don't need to chip it with those mods. You can, and it certainly wouldn't do the car bad, but you don't have to. Best to do it is with an FI installment or after a big build.

Actually, Inline-Four can reprogram early 96-98 OBD-IIa ecu's. Don't worry about changing your ecu. Just run what you have.

yea i don't plan on going vtec, you can only do so much with it, and you'll have to keep tuning it after certain upgrades. I plan on going turbo with non-vtec. Keppin it simple. And yea i just talked to a buddy of mine, he said i dont need the OBD-I conversion. We learn something new everyday!

Use your y7 throttle body. Or you will have to modify the IACV I think but im sure someone else can confirm this.

use your y7 TB with extended wires or get an automatic y8 TB and I/M. Either way is cool. If you use your y7 TB on a munual y8 I/M you will have to make a block off plate for the old IACV holes. Or fill the holes with JB Weld or similar.
