What Yall think about it?!?!? for it or against it?!?! go with obd1 stay pm6 chipped.....for a 88-91 si crx, civic hb....LET ME KNOW WHAT YALL THINK!!!!!!!

 

uhh...what engine would you be converting your ecu to

 

the easier the better.

 

For - i have one and like it for my mini me. just hook up 1 wire to the VTEC soleniod and bam you are ready to go

 

or save yourself some money and run a couple more wires. its not a lot of work if you know what to do. also i've never been one for "hacks" so i'd prefer to leave both sensors in there but thats just me.

 

it is for a SOHC VTEC motor........?!?!?! or convert to obd1 with pigtail harness and etc etc etc......

 

The Zdyne conversion is more expensive than an rpm switch.
I have done both, and the Zydne route was simpler, but and even simpler way would be to use the PM6 with some sort of rpm activation switch hooked to the vtec switch, ie. a shift light (everybody wants one of those), or that MSD rpm switch.

 

rpm switches only switch the lobes, they don't alter the timing or fuel so its not as effective as it could be

 

Zdyne is the way to go, I have been researching it recently and plan on getting it for my daily and for my freinds car. Hopefully its as good as it sounds. You get the fuel curves + a little better of a P28, and all you have to do is wire up VTEC. That is great.

 

Over two years with it and no problems run as good as a stock. I autocrossed it, HPDE and everthing just runs great. I heard some people when the switch don't mount the ecu right because different mounting points or something and they short out.

 

anybody else......please speak your opinions..............

 

Oooooohhhh, I've got a bone to pick with this Zdyne one-wire dude. Well, actually from HASport. Get this:

I called up HASport about 2 1/2 weeks ago. I asked 'em about their one-wire conversion for my Z6/Y8 motor. I described all of the details about the motor, like I need a beefier fuel map for the higher compression motor, and it's using a Y8 head, SO I DON'T NEED THE WEAK Z6 MAP!!!!!!

Over a week later they FINALLY send me the Zdyne ECU. I install it, and guess what? The MORONS set the VTEC X-over at 5800 RPMS!! I asked for 5100 RPMS!!! Well, that's okay I thought, I'll just tell them and send it back. But not before I take off the cover and see what they actually did to 'convert' this old HF ecu! Guess what I see? They put a chip with the STOCK Z6 fuel maps in there!! WTF?!?!? I asked them for stronger fuel maps than the Z6!! What part of "No Z6 maps" DIDN'T they understand?!?! ARGH!

Anyway I sent it 2nd day air back to HASport after calling them up telling what my problem is, once they recieved it they let it sit there for another 2 business days before doing anything about it! I then just called them today, very frusterated. I asked for a refund "uhhhh, we're just gonna check out the ECU. Soooo, give us a couple hours and just call us back." So I wait, then give them a call, and ask for the refund again. "Well, I forgot that this was a custom built ECU, we can't give you a refund on that since we don't carry these in stock!" What the???? How can you sell me something then say there is no possible way to return it??? I didn't see anything like that on my reciept!!! So here I am, very angry at HASport.

So what about the Zdyne ECU, or Zdyne itself? They're okay I guess, the installation was very simple, and very very stock looking. But is the one-wire a good performance ECU? NO! Your WAAAYY better off buying a Apex-i VAFC. With that you can continualy tune the motor for optimal performance.

Believe me, the Z6 fuel maps aren't NEARLY aggressive enough to fill the potential of the Y8 head. So, unless Zdyne says they can put some other program in there, don't buy this ECU.

'Nuff said.

Oh yeah, I guess I better vote right?

MrTodd = AGAINST!!!!

I may be selling my one-wire conversion ecu soon. I'm still trying to decide. If you're interested, let me know.

Specs
8500 hot rev limit
7000 cold rev limit
5100 vtec x-over

JDM EF9- Go for it...\

IMO., its better than a RPM swith
better than a Shift light
cheaper than a F-VAFC
more simple than going OBDII
u have less chances of having electrical complications if u got oBDII
its real easy to use and look stock...
u have 2 diff fuel maps for and out of VTEC
u give them the specs u wish..
if the one wire supports B16's, Y8's and Z6's then it means that they do have a nice agressive curve

 

Its supportin' a 95 GSR for the moment too.

 

i have an a6 block with a y8 head/intake and the zdyne 1 wire. cross over is 4800 and rev limit is 7800.. im happy with it and instilation was as easy as it gets.

zdyne =

 

good replies............i know theres gotta be more around with ZDYNE chipped PM6........for a SOHC VTEC.............

 

the only thing that my zdyne lacks if dataloging. its a dream to use, quick to program, and it has alot of the features that I need.

 

You probably already know my position on this. But I will say it again: GO P28!!! First off, a P28 is MUCH, MUCH cheaper than a Zdyne one wire conversion. And you can do the wiring conversion yourself in a day or two for nothing. Secondly, you can use the proper distributer rather than having some halfass setup with a stock SI distributer cobbled onto a D16Z6 head. Then there is California emissions. I could not help but notice that you live in California. And if you try to go to the ref, they will VERY, VERY likely laugh you out onto the street without a smog certificate if you try to ref your motor without the proper emissions configuration (ie without the P28 ECU, four wire oxygen sensor, proper distributer, etc.). Finally, if you go P28, you can have it modified by Hondata if you want more tunability. And I would take Hondata ANY DAY over Zdyne.

Can some one give me a price for this conversion, it sounds good , i want it for my Pr3

PRICE ???????

 

I can vouch for a Zdyne. It's good for b16a's. I've actually dynoed it baseline against my chipped pr3 and I tried 5 different programs (I can chip them) and Zdyne was a tie in first. I have a b16a with mods and works well. I switch back and forth from Zdyne to PR3, but the PR3 seems to pick up tad better in low mid end, Zdyne seems to kick hard and loud in v-tec. Zdyne programs the chips without pulling the chip out, I looked inside mine, every chip was not desoldered, he must have a 40 pin aligator adapter over the chip to program it? I dunno. Oh wells, it works. On my zdyne I also have custom v-tec 5800 and redline 9500 and it worked well for drag Might I add my original Zdyne program was 5300 vtec and 8500 redline, went I put CTR cams in, it lagged bad when v-tec kicked in, so I raised it and it helped a lot. Also the Zdyne will pass smog no problem if everything else is set stock settings.

 

AYe Jeff C which one would you say was more affective for you?!?!? Zdyne or p28?!?! and what were the differences?!?!?!

 

Personally, I cant tell much of a difference.
Are you sure?
-ZDYNE ECU Conversions ($290 to $320 depending on the ECU model)
-My OBD1 conversion: Dist. (used) $135, 4 wire O2 (used) $40, Jumper $170, Chipped P28 $? (cant remember, but your already more expensive than the One-Wire conversion).

If you plan on going with a standalone in the future, then convert to OBD1. If not, I dont see why you could not stay OBD0.

Thats what I think.

91CivicSi on H-T is using the Zdyne conversion on his hatch which has a 95 GSR motor. The car runs great! We are putting a Greddy turbo kit on this weekend. However, he will be runnin the AFC Hack for the turbo setup.

 

Mine works pretty damn well. 5300 vtec and 8800 redline makes for a lot of fun for me. I am changing to my p28 based Hondata soon but for a simple plug and play solution for decent b16 performance in an EF, I would recommend it to others.

 

just curious but who out there with the Z6/Y8 is running a PR3/PWO ecu? I am running this currently in my CRX-Z6 with the Mimic-mugen program(deleted knock sensor, vtec 5k, rev limit 10k). It runs really good with no problems after 6 months, just curious as to if anyone else is running this combo. I think it would really benefit with an aftermarket cam such as Zex or Crower with the extra fuel and extended redline.
