What ECU to use after Swap?
I recently swapped in a JDM SOHC vtec ZC engine on the car, an 88 dx hatch. The engine is just like a d16z6 but it is stamped ZC and after some research found it has 130 bhp. I have been using it with the old dpfi intake and ecu. I will swap the intake soon. I have both an Si intake and the stock Z6 intake. I was told before I could use the stock Z6 intake with an Si ECU. I just want to know and make sure I can, also Could I use an 88-89 integra ECU instead? Will both work. To Control Vtec engagement i'm using a shift light for know, later I'll get a vfac. So i do not need a vtec ecu. What do you think?
thanks in advance

Also, I forgot, I'm planning on using an Si Dizzy on this. Would the integra ecu work with the Si distributor? Can I use an integra distributor? I would just get everything out of an Si, but I cannot find any in my local junkyards, but there's a lot of integras.

Why would u use a dual cam ecu on a single cam? I highly suggest u use a p28 (obd0 -> 0bd1) as u will not get full performance with just a vtec activator switch (i know first hand - the vtec cam has different fuel maps). If u don't wanna go obd0->1, get a VAFC so u can adjust fuel and activate vtec and use a SI ecu.

I have a P28 also but I have not found any info on wiring changes. I even have the plugs for the ecu, would make it easier if I could just use that with existing harness. I'm not sure if it is possible or safe to just cut the wires and use the p28 plugs and ecu.
if not can i use a PG7 ECU 88-89 integra.
I'm sure I will not find a PM6 around here. But probably can get one from an older integra, PG7 or PR4

Can't use the teg dizzy on sohc's but the ecu's you can. It usually goes match the dizzy with the ecu but if it's odo0 and then its open game except for those dx ecus are junk. The obd0 teg ecus work with great though the higher redline is a bonus, but it's also a killer. Due to the fact that the limiter comes in at 7800 and I know honda engine are tough little buggers but stock d-series won't last long hitting 7800 all the time. I'm running a d15b2 with a z6 and pg7 due to the fact that I'm not into doing the whole ecu wiring and obd1 change and the pg7 give me a little high fuel and timing then the pm6 to compensate for when the vtec come on. Sorry for the novel.

I'll probably go with the PG7, went to a junkyard by work and they have 3 manual tranny. No Si's anywhere. I'll probably have to ebay the distributor. The resistor box I'll probably use one of a 90-91 integra. Thanks for the help.
