    Hi everyone! I changed my engine from PH16 to d15b vtec a year ago. I have a honda ESI '93. The mechanic told me that we don't have to change the ECU as it will just work the same. Is this true?

    puedeng hindi magpalit pero mas maigeng gamitin mo na lang ang ECU ng D15b mismo kasi mas malakas ang D15b na Vtec lalo na kung ang D15b na engine ay galing mismo sa EG na civic

    So naka-d15b ka na po ngayon, with ECU still from ph16...

    Sir palit ka nalang ng ECU.. p08 po yan dapat..
    obd1 kung manual, obdii yata pag matic....

    iba kasi fuel maps ng d15b sa ph16 eh...
    one basic difference nila is that vtec ang d15b, whereas walang vtec ang ph16 ng esi...

    iba ang fuel distribution maps ng vtec engines

    so highly recommended na you have to change the ecu to p08 pag naka-d15b ka na, para mas efficient ang takbo

    2 tips: 1 - change your mechanic. he should know better. your car will run by his theory. the question is: "is it running perfectly?". 2 - change your ecu to p08 immediately.

    Ah ok, so d15b matic na ang auto mo ngayon?
    Na ang ginagamit ay ph16 ECU diba?

    Change the ECU to p08, much better kung yung obdii (obd2) kasi i think yun yung pang matic and/or 3-stage...

    I think merong nagbebenta ng p08 ECUs sa virtualbanawe.com, not sure kung may stock pa siya....search mo nalang..
