just put in a pr3-j01 ecu in my del sol which normally runs a p28... this ecu threw a code but runs fine and vtec kicks in at 5700 rpms. Im buying a vtec controller so it kicks in at around 5 for more usable powerband. any one have any information about this or what i should set my vtec at?

 

d16a_? if its an a6 it shouldnt hit vtec unless you swapped heads...and even so then the ecu for the a6 shouldnt hit vtec...we need more info

 

its a jdm d16a6 from a fiero i believe, i never swapped my head but i know it's SOHC vtec.

 

???

ferio never came with a d16a6

there is no jdm d16a6 the 6 denotes that

a d16a6 is not an sohc vtec

a d16a6 is from an 88-91 CRX si or civic SI

you probably are thing d16z6, in that case the PR3 is for a b16a motor, better off selling it and buying a p28 to get it to run right, they cost about the same, other wise you can chip it and load it with a p28 BIN/ROM which i can email to you.

you need a chip burner, soldering skills, and the faq from pgmfi.org click on how to chip my ECU

 

ok then its a d16a_ what? i know its a d16a and i ordered it from japan, i know it's SOHC and i know it has vtec, i can show you pictures of my vtec solenoid...

if it is truly a JDM d16a then its called that d16a. pretty rare engine thats probably why you couldnt find info on it.

still the PR3 is not the proper ecu for it. a p28 will be the best soulution for that particular motor.

yes a JDM d16a is sohc vtec........you stated numerous times its a d16a6 which is NOT the same engine. be careful before you type motors...........................the NUMBEr does matter

d16a1 - dohc non vtec first gen integra
d16a6- sohc 88-91 crx si
d16a- JDM sohc vtec

see how there is a diffrence?

but what you can do is go ahead and show the motor stamp, ill tell you exactly what motor it is.

 

thanks that clears a lot of things up... ill take pictures in a bit... so my engine number is d16a no other numbers right? thats weird...

 

here you all go its a jdm d16a sohc vtec



i have a p28 ecu but i was fiddling with other ecus and the pr3 kicks vtec harder, im thinkin it has something to do with its fuel management.

 

anyone have any input?

 

your vtec needs to be a 4800..best bet would be to just get a p28 ecu...if you need one i got 2 for sale.

 

haha i've got 2 sitting in my car, but vtec hits harder and my car seems faster in general with a pr3 ecu, i have no idea why, but ill set that one for 4800 and send it in to get it chipped... i wonder if the fuel maps are different or something like that...

 

does a stock ecu, (any type) recognize the difference in octane, whether it be 87, 89, 91, etc?
