Paying for any ECU with VTEC is a waste of money. Just get a P06 or P75. Far more common, and cheaper. They can also be converted to VTEC if you need it for some reason. Also, a VAFC or SAFC is a waste of money. Why use a crutch that works *most* of the time, when Crome and Uberdata allow you do everything internally with just the ECU?
Well, I just got this ECU

I got it mostly because I want to compare it with the PK2 ECU in term on internals. No one on 3geez reported to have an 88-89 PH3 ECU ao I wanted to get better knowledge on it.
I already got a P06 and a conversion harness to go OBD-1. I guess I will do different Dyno runs with the Pk2 and PH3 ecu to see if they have any power curve difference.
sory, but is it possible to make b20a power from b20a1 :))?
I've already tried, but was unsuccesful to gain that power. I was also having problems with the EGR system since I didnt have it on my B20A2.
I found that I lost a good bit of power instead.
I swapped from a B20A to my B20A2: cams, exhaust manifold, distributor and crank sensor and PH3 ecu.
i heard that the difference is ECU and injection, am i right? is it worth to get only ph3 ecu? how can i tune my b20a1? maybe everything will be waste of time , money, etc?
In my opinion, yes a waste of time. I think the best thing to do, is to get the distributor and crank sensor from a b20a (or from a 88-91 lude B20A7 engine) and then convert the ECU harness to OBD1 and run a chipped programmable ECU.
Another option is to use the ecu from the 88-89 lude B20A7 engine, since these engines doesnt use EGR or O2 sensors either. You will still have to get the other distributor and crank sensor.
how much can i espect getting the ecu, distributor and crank sensor from hp3
?
Well I'm not sure since when I did that I lost power instead of getting more power. But I'm not sure if that was because I couldnt get the EGR system bypassed.
Which means that I still havent figured out what seperates the B20A from the B20A1/2 in terms of power output.
