I called corksport, and they say that the weren't able to fnd different listings for MTX and ATX chips, but every other place says that there is. So I'm again at a loss about what to do. The car is running better the last few days, but I think the timing is a little retarded, and the mixture still doesn't seem quite right, but those are minor problems.

engine is very hesitant, and still feels like it doesn't have much power. Still purging air from the coolant, and this weekend I think I'm going to pull the headers and replace them with stock while I have a flex pipe installed in place of that rediculous ball and socket joint.

any suggestions of what else I can check for on the engine that might give me some idea why it is not running right?

Thanks again

hey guys....i am off to asia and buying these things

ZE cams, IM, TB, ECU...spacers and ported will be done also....

now i am going to put them in/on the original 03 block.....will this work and do i need the mx-3 VAF....or should i not get the ECU and stick with the stock VAF

also my engine seems to be looseing a bit of oil and i am thinking of getting the entire engine, which would be a pain to ship but what i am wondering is what HP gain would the cams IM, TB and proper Ecu give compared to the actuall engine swap....thanks this is great

As far as I know, the flashing hold light occurs when you have an ATX error.... this probably means that your new J-spec ECU is sending information that is incompatible to you tranny (or tranny computer if you have one) or you have a manual ECU....
just my two cents worth

(Yes.... I have a constatly blinking hold light... partly because I got rid of my auto in favour of a manual tranny)

cheers

our ecus have both atx and mtx information in them.. when changeing over or resetting the computer , it has to learn everything all over agian.. I know for a fact that your ZE is still being adjusted by the ecu , because the jumpy idle is normal... Apon my swappage I had to let the car sit for a few hours running and the idle would be all over the place... If you just disconnect one of the battery terminals to reset the ecu, then reconnect it after 15-20mins start the car up and just let it run for an hour or so until the idle starts to normalise.. IT SHOULD... It will idle alittle high 750rpm which is where mine idles at, but if it is a constant idle and doesn't go above 1000rpm then thats fine....
THe power issue could be plugs and wires, as mine is doing what you discribed to a T.... My plugs where replaced and wires will be soon as a couple of them are missing bad.... Also check to make sure your VRIS Seilenoids are working correctly and opening like they should be... The timing is yet agian the same as the idle, the ecu has to learn the engine over agian.... but I dunno I have an MTX a-spec ecu and vaf and alls I have is a stupid egr code and a vac leak some where

but the behatch runs stronge even witht he missing plug wires

, then yet agian my engine also has barely any miles ( 10k at most form the shop estimate) muahahaha

**Silenc3r** · 9-9-02, 12:52

It's running a little better now.

I'm going to replace the plug wires next weekend, and possibly the dristributer.

I'm noticing a lot of lifter noise from the rear bank, and I still haven't tracked down where the gas smell is coming from under the hood (but I have a pretty good idea now). So this weekend I've got to pop off that rear valve cover and adjust the lifters and swap out the fuel rails for the ones on my 03 to see if that makes the smell go away.

I've still not been able to get the guy I bought the ecu from to replace it with the right one, so I've decided to just replace the tranny with a 5-spd this winter. For now I'm installing the tranny cooler and a remote filter kit so I can keep this tranny running as long as possible.

Thanks for all the advice. Still tweaking, but getting the thing much closer to what I'd hoped for when i bought it.

Folks, just a reminder: This thread is intended to be a concise FAQ about ZEs, not a running commentary about ones progress with a particular car or for generalized discussions.

Being an FAQ, the intent is to condense all important, frequently asked questions into a short, "executive summary" of information. Please, let's keep it this way. After a few days, I'll probably come back and do some culling of posts here I deem to be not in the spirit of an FAQ. Please do not, therefore, take the possible disappearance of your post as an affront.

I'll try to take valuable tidbits of information from each post, where possible, and condense them into a single (or perhaps two) post in a "Q&A" format (perhaps, I'll see what works...)

Thanks for your attention.

Where can I find a ZE shop manual?

I'm looking for the tuning specs on it, and the tolerances to set things to. I have to adjust the HLAs and or lifters or whatever it is, but I don't know if the adjustment is going to be the same for the ZE as the 03. Plus I think it would just be a good idea to have the shop manual handy in case I ever have to bring it to a shop.

My local dealer said they only can get the 03 manual and that there is no documentation for the ZE. I just find that hard to beleive.

Any suggestions?
Thanks.

Regarding an aftermarket FPR on a ZE:

The post says 46psi at WOT...is that with stock or aftermarket fuel pump??

Also, who has done dyno tuning to see where the optimal psi is at??

I have mine at 46psi (wot) and it runs better than with the stock fpr.

**easyBob** · 10-9-02, 19:29

I don't think you can change the stock fpr psi... And those are just common settings for a non modded ZE (no internal work).

I have my heads,spacers, and IM ported so I had to set my fpr to 55psi (It was overheating-->more air than fuel).

The best things to do are to get a EGT gauge or dyno tune....I never have been to a dyno or know what it involves so your on your own there.

**ssjgokou** · 10-24-02, 3:58

I've been looking all over the site, I havn't heard anyone
talking about swapping parts from the KLZE to KL03, such
as the manifold?

**Silenc3r** · 10-24-02, 12:28

I remember a few, but I don't think anyone ever covered the new Vac line routing. I think you would just use the ZE vac routing for the ZE manifold, though. I think in the end you'll have one connector you don't wind up using, though. I wound up with one electrical connector unused from my stoak wiring harness when I did my engine swap.

Other than that, most of the things are the same. If you keep using the stock ECU, though, the VRIS opening points won't be right, so you won't gain the full HP potential of the manifold.

ScubaSteve, I think, had posted a diagram on how to hook up all the vacume lines on the ZE for the engine swap. I'm pretty sure you can use that to just do the mani. I wound up using that diagram, and one I found on probetalk to do mine.

good luck

**easyBob** · 10-24-02, 22:04

You said it Silenc3r. There is one metal tube by the TB side of the IM that I'm not using and there is also an extra coolent temp sensor I believe. It's just sitting there, not being used.

**Fastest95PGT** · 10-31-02, 23:07

Hey Mike, time to come through and WEED! My ZE should arrive tomorrow and will be installed next week and I'd love to be able to use this thread a little more.

Time to gank all the posts related to peoples troubles since not many had any actual resolutions posted that weren't mentioned in the first post. Thanks!
