I have read a lot of people say that they have a chipped p28 ecu(92-95 civic ex)
for their motors...especially for the B20vtec. Whats so special about it and what chipped program are most using.....

Greg L

There easy to find, cheaper than b series ecu, have VTEC, when chipped for hybrids, can run a b series motor without knock sensor or IABs for b18c1 which makes it easier cus u dont have to wire that junks up.

somebody correct me if im wrong on anything please.

whats is the IABs

Greg L

it controls the secondary intake runners on the b18c1 intake mainfold

yes, WannaBFast is right on the money, its avaliblity and price that makes the P28 an excellent ECU, as you know, once chipped it will work the same as a P30 or P61 that has been chipped....

but a fraction of a cost, price of a P28 + chipping is alot lower then P30/P61

also P30/P61 are rather rare ecus as they were only found in for 2 years in OBDI cars, which were sold in very low numbers

pro's: bang 4 the buck, nuff said... a chipped p28 will run about the same as a stock p30/p72/p73, except you will get slightly better gains and can be reprogrammed to match aftermarket parts better than a stock ecu will do.

con's: lack of IAB for GSR manifolds, no knock sensor (bad for turbo hybrids)
obd1 only

how much do p28 ecu cost?

yes if you have 92-95 SI hatch it has a P28 ECU. And yes re-chip and sell the ECU coming with your motor.

I'm doing a tranny conversion from auto to manual on my 96 dx I was told to get a p2p Could I use a p28 instead?

If you don't have to pass inspection with the scanner.

First, you're replying to a 14 year old thread.

Second, only the 92-95 Civic Si and 93-95 Civic EX came with a P28 stock.

Your VX has a P28 because it has a JDM engine. A stock VX has a P07 ECU.

I got complete d16z6 swap it comes with p28 ecu with chio how i know what kind of a chip is that ???

thathondakidd

was told the p28 ecu was good route for a K24A4 power build with head swap and different pistons. but seeing mostly B series info. was also told to look at a Kpro 02-04 rsx type S PRB ECU but that says it's not legal. not well versed in ECUs so help is appreciated

JRCivic1

You WILL need K-Pro. The base ECU foundation could be one of many options, but a P28 isn't one of them. The PRB is the top choice... although if you aren't running a 6-speed transmission, you can use the PND or PNF ecu.
