help with my "zdyne" ecu
 

ok so i bought a bunch of stuff for a great deal and i was told this ecu is a pm6 chipped with the b16 program with 1 wire vtec by zdyne. Then i took a closer look, it says it was made in 87 which i was completely unaware of (unless they were made earlyer than put in cars) kinda like the 06 cars will come out in 05......and then i looked inside and i was thinking i would come across a 28pin zif.....but its huge (im guessing the 88-89 kind)......is this a real zdyne? is the pin for vtec the same as a pr3 ecu?......its gonna run my crvtec for a bit....thanks!

what car you puttin the crvtec in? that's n obdo ecu that's for sure, hope your odbo also or that would suck. hope everything works out for ya

Re: help with my "zdyne" ecu
 

of course its obd-0.....im not retarted (or so id like to think) i was just really supprised with this ecu....and wondering if i wanted to make any changes it was at all possible with the 87 ecu???

Re: help with my "zdyne" ecu
 

thats a ZDYNE ecu, however, its not a GOLD SECU or you would have a way to hook it up to a computer.

ZDYNE replaces the processor, not the chip like we do with TurboEdit

You're going to have problems because the fuel and timing maps in that ECU are for a 1.6L Vtec and you are going to be running a 2.0L vtec...and it has a set VTEC point

Not good, you'll need an (V)AFC or something...

Re: help with my "zdyne" ecu
 

yeah, i would suggest running an afc with it also, unless you just ditch that ecu totally and go with something else. are you planning on boosting the motor?

Re: help with my "zdyne" ecu
 

well im thinkin im gonna go with a little all motor fury lol......its gonna be in my daily driver and i really dont want to blow up my beatiful b20 with 6k kms......i was thinking i would have to use a vafc or something, i just had doubts about the ecu....i will more than likely sell it and go obd-1 (im assuming uber is better for all motor than turboedit).....

Re: help with my "zdyne" ecu
 

Why...

The only reason I'd tell you to go Uber over TE is because you are running VTEC...

Re: help with my "zdyne" ecu
 

The vtec maps are very important to the engine. You would have to ask blundar how far the map switching code went in the OBD0 stuff. I know we discussed a lot of ideas on the vtec code but I got too busy to develop code for it and eventually left the project for a standalone.

Sellout :P

Nah, I meant why else besides the fact that he is running VTEC.

Re: help with my "zdyne" ecu
 

ftl, fts, vtec support, live edit, yada, yada, :-X

Re: help with my "zdyne" ecu
 

FTL - TurboEdit has it

FTS...ok, how much do you really use that when you arent at the track

VTEC - I can do VTEC with TE, yeah its not 2 maps...but who cares, still works same really

Live Edit - yeah I have to buy a $175 piece of equipment to Live Edit...and actually ROMulator does work, Parker just needs to tweak it a little and RTP Board support ($45) WILL be added soon.

yada, yada - ???


Oh how bout with TE:

I save myself from buying
- new ecu (40-175 depending on if its a P06 or P72)
- a conversion harness ($100 - $125)
- a used OBD1 distributor ($50 - $75)
- a 4-wire O2 sensor (can be found cheaply at a junkyard)

I think I'd rather take the $200 - $300 and buy more go fast parts...not to mention TE has great support for the 2.5 Bar Map sensors now.

How's 3 Bar working with Uber these days???

>:D

Re: help with my "zdyne" ecu
 

pretty good actually ;) i've tuned a few obd0 cars with turbo edit (i'm sure not as many as you), and uber data, uber data is much easier to get a good tune with, and all of the guys who i've talked to who used to be obd0 running/tuning turbo edit, then convert up to obd1, say they will never go back. every car i've done with te, it seems to be have an unforgiving rich spot that i can never get rid of on tip in?? maybe it's just my lack of experience with it. either way, i've used both and am partial to uber for a reason, it owns. btw, romulator is close, but not quite rtp ;D te is definitely the best obd0 rom editor, but by far the best rom editor (not saying that uber is either). jason has done great things and come along way with te, and i'm sure it will only get better, but uber's been around a lot longer and had a lot more support and testing, thus putting it where it is right now.

Re: help with my "zdyne" ecu
 

How do you figure?

TE was doing live updates with ROMulator a year before Uber...its just there are problems that havent been hashed out since Parker has been busy.

Re: help with my "zdyne" ecu
 

do you have to hit 'upload'?

Re: help with my "zdyne" ecu
 

Nope....LIVE EDIT

Re: help with my "zdyne" ecu
 

te has only been out a little over a year ???

Re: help with my "zdyne" ecu
 

Try Summer of '03

Re: help with my "zdyne" ecu
 

i'm sorry, a year and a half :P

Re: help with my "zdyne" ecu
 

I'm guessing this is because the OBD0 rom still thinks it's controlling 240cc injectors as far as tps enrichment is concerned.

Re: help with my "zdyne" ecu
 

wow you guys got crazy on that ---- lol.......i honestly think either would be a ---- load better than a vafc which is my other option, what would you rather start with, pr3 or pm6? im thinkin pr3 due to its allready vtec'ed out lol
