i gota 97 civic dx with a d16y8 in it with a p2e ecu. what would be the outcome if i put in a p28 ecu?

 

it would not run correctly. its the wrong ecu.

 

Also would i run vtec if i hooked up the jumper harness?

 

Oure saying the p2e is the wrong one? And p28 would run better. And what bout the jumper harness?

 

Nvm misread that. I thought p28 was the stock ecu for my engine though

 

I believe that the P2P ECU is the correct OBD2 ECU for the D16Y8.

 

p2p is the auto ecu

 

I don't believe so. It should come in both auto and manual versions:

No, they came in automatic and manual versions

Correct.

Any to anyone that wonders why a P28 wont run Y8 properly it has to do with differences in ignition timing between the Z6 and Y8.

 

Ok thanks yeah i got it withthe car when i bought it. Didnt know if it was a change or anything

 

What about the jumper harness? Whats the info onthat

 

get a ob2a-obd1 jumper harness. It will run, but not sure how good. Not sure if you would needa tune or not.

 

I have one ill post pics tomorrow ill call my local shop and ask

 

well i should run good with no problems thats what i have in my car with same motor no problems so far

 

You have a p28 ecu in ur d16y8?

 

I'd kind of forgot about this, but there is an OBD2 P28 used with Y8s, its found only in the '96 - '97 Del Sol Si and I believe its just a P2P with a different part number.

 

Ill post pics of it all timorrow and you guys can let me know whats up

 

In my car now:

what would happen if i put this in there: even the jumper harness would i run vtec?

 

You can run the engine with the P28 with a jumper harness assuming the car is a 5 speed, if its an automatic it wont control the transmission. It will run poorly due to timing differences between the Z6 and Y8, the only way it will ever run right is if you get it chipped and tuned.

 

i wouldn't if you are in a state that does a ecu check on 96+ vehicles. OBD II.

lots of states do it now, just to plug it in and check codes. if its a p28, they can't plug it in, then it wont pass.

cali = no go with no way around it.

 

the p28 is stock for the d16z6

 

Yeah its a 5 speed ill hook it up see what goes on. Is it smart to run a chipped ecu on a stock engine? I live in pa i dont think its a big deal. Ill find out
