Hey whats going on. I have a D15b7 with a d16z6 head im about to put on. i have everything but the vtec ecu, looking to get a p28 ecu. Anyways i need to know if you can use a non vtec ecu on a vtec engine for a while. its only temporary till i get more money for the ecu. any help, ideas, etc would be great. thanks

 

bump for info

 

if you MUST drive it you can, but dont rev it past 3 grand, dont get anywhere near full throttle, and make sure you use high octane gas.

 

I would say yes, only cause or atleast i would think the only differance would be that at certain RPMS your Vtec kicks in. I dunno for sure tho.. Anyone else want to correct me?

 

why not rev past 3k?

 

cel

 

because the fuel and timing maps are totally differant and as the compression (rpm) rises the potential for detonation increases and that will *** your motor

 

the maps at all rpm are differant because of the size intake/exhaust ports the compression ratio, manifold design and 100 other things.

 

ok cool. keep the help coming. more info.

 

Point taken.

 

Thats pretty much it.
I ran a P2E ECU on my y8 motor for like a month. It threw a code for too lean. And was also in limp mode for some reason.

So, You can do it. probably wont hurt anything substantially, But i wouldnt do it forever.

 

ok cause it would only be for like 2 weeks cause then ill get paid and be able to swoop up a p28

 

oh also what other ecu's would work with the mini me?

 

ya when I bought my car it had a P2E on it (97 EX). I didnt realize it for a month or so since this was my first honda i wasnt exactly sure wtf was wrong with it. Just that it was way too slow lol. So yes it will work, but u wont get great gas mileage and it will run like crap.

 

ok well imma dig a little deep in my pockets and just get a p28. thanks guys. oh nd im pickin it up tmmmorow

 

good choice.

 

i have a vtec ecu with a non vtec motor mine runs fine has idle roll if you try to kick vtec in tho. i dont think you should run a vtec ecu with a non vtec engine tho.... cant be good


i have a p28 ecu i might let go of for the right price

 

I am running a chipped P06 in my car and i have the same exact swap that you are doing. Everything runs great but i have to run a high octane gas.

 

when i bought my 94 ex it had a z6 with a p06.
i drove it that for a few months (drove fine but no vtec, even over 6000+rpm), then modded the p06 for vtec.
since then i have gotten 2 p28's and 2 more p06's.
they all have same circuit board, 1720, and the same components except the p06's didn't have the vtec components.
there maybe other boards in a p06 but all of mine have 1720s.

cliff notes:
answer to OP's question, YES if its a p06
p28 = p06 w/vtec components

 

itll run just fine. no vtec, but whatever, it works. it wont detonate, the compression is low, the ecu can compensate for the differences

 

ok cool. yeah how would i get the chip for the po6? if its cheap then ill just do that

 

google it or look on here.

 

I have the same setup on my 93 civic and with the stock po6 non vtec it ran fine. But when I got the chipped po6 and connected the vtec it was a whole new world So drive it it will be ok or at least mine did fine.
