    So to start off, I was just switching through the gears when my battery light came on and my car died. It cranks over but doesn't start. Took it to a mechanic after replacing parts we thought it could've been and he couldn't find any mechanical issues with it. Still won't start. I was told it...
  5. ECU Tuning
    New here and have been reading everything on ECUs and tuning, but it hasn't helped. My searches have not shown me any answers. I bought the car w/o knowing the ECU was changed from the stock P5M-A52 to a JDM P5p-003. The engine is a Vtec H22A4, and I'm not sure about any modifications. Of...

    Hello, I am new to the prelude world. I just picked up a 1996 Prelude with the H23A JDM blue top in it, SI 5sp, and the wrong ECU... The guy who sold it to me gave me 3 ECUs and said none of these are actually for this setup, but the P13 has been working alright. The car randomly revs up and...

    Hi! 1997 Prelude Swapped Auto to Manual Was using Chipped p28 ECU. I recently converted my p5m ECU from automatic to manual (paid a TV guy 25$ to do it) so that I can remove the Chipped p28 because I plan to forever stay stock and pass CA emissions.... I disconnected my battery... Then...

    Hi I'm new here. I was directed here upon joining a prelude page on Facebook. I have a 1991 Prelude Si that was given to me for free by a neighbor. It had been sitting in his front yard for 12 years. Her wheels were stuck three inches into the ground and she looked like she belonged in the...

  12. ECU Tuning
    I have a 2000 prelude with an automatic to manual swap and i have a check engine light on because it still has the original ECU. I was wondering if it would be easier/cheaper to go and buy an ecu for a manual, or if it would be possible to take it to a tuner and get it fixed.
  13. 5th Gen
    Please bare with me and if you think you can help please read. That's the code i'm throwing out ever since my lude started running wonky. It starts up fine and sounds good for about 2 minutes then it idles bad and is doing everything it can to stay alive. I've already tried another MAP from...

    Hi all, I have a complicated and frustrating situation that I could use some advice on. Here's the background info: - I hydrolocked my 1998 automatic base prelude. (F***!) After measuring the piston heights (and seeing water in a cylinder), it was clear that I bent a rod pretty good. I opted...
