just wondering if a zc ecu is worth to pay the 100$ for i have the teg ecu right now, any performance gain ??

SilverCRXSi

No performance gain (as I'm aware) the ZC has a rev limiter (7200 RPM) and a speed govener to 180kph, while the 'teg ECU has a rev limit of 8000 RPM (could explain why some people blow their ZC's) but the 'teg ECU has no speed govener.
People usually go for the 'teg ECU cause they're easier to find and cheaper. Personally I'd go with the ZC ECU since it was designed for the ZC engine.

Also from my experiences, people with 'teg ECU's usually seem to blow their dist. a lot...

My 2 Cents...

umm sorry..but the teg ecu also has a rev limiter at 7200 rpm. I have tested it many times in my car and won't budge over that limit. The limiters are the same with both ecu's. The zc ecu has a speed limiter of 112 mph, not sure about the teg ecu but this shouldn't matter, hopefully. The zc works best with the zc motor but I still can't find an explanation to why it's better. What difference is the zc to the teg ecu? no one can answer this question and they both perform the same. I never had any problems with my distributor and I don't know how the teg ecu can affect it. I even had an si ecu in my car for a long time and it never affected anything on my motor so using the teg ecu won't affect or break any parts on your motor.
Personally I would stick with the ecu you have, it's fine. But it's quite hard to find a zc ecu and especially for $100 b/c the zc ecu's usually go for a minumum of $150 and go up to $200. If you can, try to sell your teg ecu and grab the zc do it, but if not the teg will be just fine. IMO I would spend that $100 on chipping your teg ecu.
This site can also convert your current ecu into a ZC ecu http://www.zdyne.com/

where is a good place to get my teg ecu chipped, except for zedyne they are way expensive, plus ou need to ship out your existing ecu to get reprogrammed. I want to find a place that will add chip my ecu for better performance but not so my gas milegae goes down the drain. i hear some guys with that mugen chip get like 250 km on a full tank of gas that sucks

this guy does ecu programming http://www.allmotorhonda.com/techpages/ecuchipping.htm
I also know someone in person that does chipping but im not sure how much, let me know if your serious and I can find out how much he does it for. The guy I know can do any chip for you like mugen, spoon, etc

cluster

You know with all this ZC talk not one person has mentioned the Cam sensor

Also if you use the tegz ECU it will eventually throw a code for Electric overload

If you can get a ZC 5 Speed ECU jump on it

90% of the ZC ECUs out there are auto and most people have no clue that their car is only running at 75% - 80% of what it could be

SilverCRXSi

cluster is correct. The electric overload is prob. what leads to the dizzy's blowin.
The differences b/w the 2 are that the 'teg ECU has a different fuel curves (runs lean I think, whatever that means) while the ZC is normal. (Some explained the difference to me at N8 last year, so I don't remember exactly.

I myself am sticking with my Si ECU, until I can find a ZC ECU(manual of coarse)

The differences b/w the Si ECU and the ZC ECU is that the ZC has better fuel curves and with the SI ECU, it runs rich.

My Blue Si: The only ECU's I've heard of that have a 8k rev limit (and not redline) is the Si/ZC ECU. PM something... PM6?

imported_My Blue Si

sorry...what do u wan't me to pm you about?
The teg ecu also has better fuel curves and timing than the Si ecu.
Si ecu is ok, teg ecu is much better and the zc ecu works the best.

Rice Burner

I would stick with the Si ecu unless you could get a 5spd. ZC ecu. You say the teg ecu has better fuel curves and timing then the Si ecu, but that's nothing an AFC and alittle work with a timing gun can't fix. You would benefit this way much more than with the teg. and no code's.

imported_My Blue Si

don't forget the limiter, the teg ecu limiter is greater than the si's limiter. I wouldn't recommend advancing your timing unless you've got some work done to your car especially cam gears. I know many people that have done this and get stuck stranded at the side of the road b/c there sensors are all shot. I guess you guys can do whatever you wan't to your car the cheap way but you'll be paying for it at the end run. I also asked many performance shops about doing this and they all told me not too unless you've got some motor work done.
Like I said, he already has the ecu, might as well chip it and it will run much quicker than the zc ecu.

Rice Burner

Si ecu doesn't have a speed limiter, and if your talking bout rev limiter they're both the same at 7200. Yes since he has the teg ecu he might as well stick with it but he's Si's ecu would have been fine.

SilverCRXSi

PM6 I think thats the code of one of the ECU's (Can't remember though)
The Integra ECU has a higher rev limiter then the ZC/Si ECU's thats why people blow them.
Oh and the Si ECU does have a speed govener, it just doesn't kick in 'till about 205-210kph, while the ZC has a 180kph speed limit.
Don't ask how I know about the Si ECU. lol

DX SLEEPER

okay how do i tell the diffrence between a 5 speed ecu or an automatic ??? i have the si ecu right now does the teg and zc just plug right in ???

DX SLEEPER

bump come on guys anybody know the answer to my question, how do i tell apart manual from auto ecu ??

SilverCRXSi

From my understanding the ECU will flash a bunch of codes (not sure which ones)
The only way is to test out the ECU before you buy. There is no way to tell just by looking at it.
check out www.thezcresource.com , I"m sure they could tell ya more stuff on there.
I hear they're very knowledgable on there.
Good luck!

PErsonally though if you already have the 'teg ECU I'd keep it but just make sure ya dont go rev happy.
