Right now i have a test pipe installed on a obd2 prelude and its throwing a cel.

if im gonna keep the pipe on the car i dont want to pull the clock/radio fuse all the time and mess with all that garage to stop the ecu from learning... other than doing the work around on the car from NTPOG with splicing wires and all that trash.

I can get a hold of a USDM P13 ecu with this code : 37820-P13-A11 MT, is that correct? because i heard of the 2w / 4w issue, which doesn't apply to a 5th gen due to no 4ws... so what im getting at is, which type of obd2 conversion will i have to get if i get a p13... because there is a obd2a and an obd2b? the b is for preludes and integra/accords right? but it says you have to have the EGR blocked on the car? and p13's have an ecu or something like that..

basically im trying to ask, is it worth it to keep a damn test pipe to buy a p13 obd1 and harness?

keep in mind i plan to get a vafc in the future or hondata... Thanks!
