swap help

[b18b coupe]

ok im 16 yrs old and new to forums. i bought a 94 coupe dx. i just recently swapped out the d15 for a b18b. i am still using my stock d15 ecu and stock d15 spark plugs and wanted to know if getting the correct spark plugs and ecu with a 2-step help. thanks

honda plugs are honda plugs, they're all interchangeable.

You'll probably want a plug that burns a little hotter, and gap it a little shorter.

As far as the ecu, ABSOLUTELY get rid of the d15 ecu and pickup an LS ecu. I've heard you can run an OEM p28 with an ls without problems, however I don't know that personally.

oh aight bro thanks. bcuz now it runs better then when i had the d15 but i feel it lags up. some guy is selling me a chipped ecu rev limit at 10k and 2-step for 100 should i hop on it??

what ecu?

obd1 obd2?


On the vin code on the ECU there will be like 6ish numbers then a - then 1 letter and 2 numbers, then another - and another 4ish letters. (I may be off on the numbers before/after the 1st and 2nd - marks, but thats kind of irrelevant to what you need to know)

Example:

654684 - P13 - 1324


The middle THREE is what will tell you what the ecu is.
