I just recently purchased a dohc ZC to replace my hydrolocked sohc zc and need some help. with the sohc, i was running the pm6 ecu and just wondering if i should upgrade to the pm7? is it worth the money? help me out DOHC ZC owners!!

 

go pm7

 

a lil explination on why.please

 

Pm7 is the Dohc ZC ecu right? It should be a no brainer why you should get it.

1. It's the right ecu for the right engine
2. Higher rev limiter
3. Proper fuel and timing maps (integra ecu runs rich, Pm6 runs lean)

These reasons sound good enough for you?

 

SOLD! just wanna clear the smoke on the subject thats all! thanx y0!

 

LOL. PM7????

You want the PG7 - it comes from the '88-'89 Acura Integra LS (5spd). The D16A1 motor is the closest relative to the DOHC ZC that we have. If you used a PM7 ECU, the motor wouldn't even start up.

 

i use a PM7 and my car starts up all the time every time. I say go the PM7 right ecu for the ZC

 

The PM7 ECU is the 88-91 Dx ECU. You are using the PG7 ECU. If you had a Dx ECU in your car, I promise it wouldn't start. Think about it, how could a 2-injector ECU control 4 injectors?

PG7 = '88-'89 D16A1 Motor
PM7 = '88-'91 D15B2 Motor

PM7 is the DOHC ZC ecu. i got it with my engine swap from japan and it works fine and starts the car with no problem

 

I think the PM5 is the DX, PG7 is the TEG. I am almost 100% sure, I know for sure that the pg7 is teh teg.

 

PM7 = DOHC zc ecu

PM7 is best but cuts out at 180km.

I just did a DX to Dohc ZC swap. My DX ECU is a PG9. I'm running the PG7 (89 integra ECU) in my ZC with no problems.

 

yeah but you can get a mugen chip to take care of that little aspect for you

 

Well then save your money and time looking for a PM7 and use a 90-91 si ecu and chip it.

I posted my dohc zc dynos of Mugen vs PM6 if you search you will find it.

 

i've ran all 3 (pm6,pm7,pg7) and the the pm7 is most def the way to go!!
the pg7 does have a higher rev limit(7800),but the zc only has a rev limit of 7200 so you wouldn't wanna rev 7800 anyway. the pm7 does have a speed limiter on set at 112 mph,so if you wanna go faster than that you would to have it rechipped. the pm7 is was made for the dohc zc!!

 

Why don't you just post the link for the dyno results that way all of us don't have to do individual searches. I'd definitely like to see the graphs.

 

 

i ordered a pm7 ecu from some one on this board. the thing it's a PG7 and also hes sending me a PM8. what ecu is the PM8 out of?? will this be okay on my car between the two, which should i run?

 

PM8 is the d15b6 HF ECU..

 

im guessing that it wont work in my dohc zc b/c its for a DFI right?

hf computers are multiport, i sent you that one as well just as a backup, i think i did more than my part by giving you two ecus for the price of one!

 

just wanted to know what i was getting thats all

 

You already have a PM6? So why don't you send it to Adrian at http://www.hyperducktuning.com ?

 

PM6 : 90-91 Civic/CRX SOHC Si (D16A6)
Mugen Gymkhana program
Rev limit: None
Dyno/Tests: Throttle response improved, good all around program, runs less rich then PG7 but more gains.
RPT Drag program
Rev limit: 8500rpm
Dyno/Tests: Low end seems rather to feel closer to stock, top end greatly improved.
Honda ZC program
Rev limit: 7200rpm
Dyno/Tests: More aggressive then stock PM6 good for ZC DOHC motor.
Honda Euro ZC program
Rev limit: 7200rpm
Dyno/Tests: More ignition timing then stock PM6 good for ZC, SOHC with mild bolt ons motor.
Vision program
Rev limit: 8200rpm
Dyno/Tests: Excellent through out powerband, improved maps, perfect for very mild cam.

 

Uhh the zc civics cone factory with pm7 so where do u get that info from
