Default 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.

Your Si ECU will work with the with either intake. A teg ecu will be fine also (<91).

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 was using a P72 on a D16z6 once and she flew al the way up to 8k RPM. no problems. i like the fuel curves and it seams to react better. that is why i would use a DOHC program on a damn SOHC.

Thanks for the help. Makes sense. I need to get a distributor now and can finish this up, hopefully this weekend.

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

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.
