CWQ3 swap into a early 99 zx2

[turbozetec]

I just bought a 01/99 model zx2 and want to install the S/R ECU in it. I have been reading in here that I will need to install a new CCRM. I have been trying to piece together a few posts, and Dont really understand what all I need and have to do. What all do I need to change and what do I have to do to put the S/R ECU into my early 01/99 zx2.

THanks for the help

this guys also did one in this thread might help.....

So all im going need is a ccrm out of a 99.5+ zx2 and the CWQ3 ECU I wont have to do anything else it all will plug in and im done?

[mellowness65]

you have to redo the a/c pressure switch. I swapped that whole harness just to avoid a cut and spliced harness

[DOUGIESTYLE]

You'll need a 4-wire MAF with separate IAT.

You'll need a 4-wire MAF with separate IAT.

This is incorrect. The NEED of a 4-wire or 6-wire is only a preference. One can use a 4-wire MAF + external IAT with a 99.5+ PCM, and one can use a 6-wire MAF with a 98-99.5 PCM. We only use 4-wire and 6-wire designations as it is easily and quickly to discern. The changes that effect the way the vehicle and some of it's components operate are in the A/C pressure switch used, the CCRM, and the wiring between these two items.

If you read over the S/R PCM swap how-to that Cyberman wrote ages ago, you will notice that there is no alteration to the version of MAF used.

The how-to I referred to above is in the first link that pissdrunx16 posted.

Read it and you will see that you will nead a 99.5+ CCRM, 99.5+ A/C pressure switch, some wire to splice A/C switches/sensors and the CCRM, and whatever connection method you prefer to connect wires together (i.e. soldering or crimp connectors). If you want to be "clean" or avoid splicing wires you could swap engine bay harnesses as mellowness65 did. This way is a lot more complicated and involved, but it yields much more "professional" results.

is there any gains over the CWQ3 ecu and a tuned chip? Im thinking there isnt much performance to be gained out of a custome chip if the cwq3 makes 146hp.

[DOUGIESTYLE]

I have a Vit tune on my CWQ3, and felt the car with alot more oomph after installing the tune. The 146 is estimated CRANK horsepower. Alotta drivetrain loss before it hits the pavement. Get a Vit tune before he's done with tuning again.

Vit is TheGhostintheMachine. He's well known around here as the server admin., a real pain in the ass, and one of the most knowledgable tuners for ZX2s. Shoot him a PM.

[turbozetec]

Should I buy a chip with his tune rather then buying the S/R PCM?

That will probably make more of a difference, but you'll also need a device to get the tune onto the PCM as well.

[DOUGIESTYLE]

I dunno if Vit flashes PCMs. A far as I know, he only tunes flash devices. I shoulda been more clear. He tuned my Xcal2 that I flashed the PCM with.

[turbozetec]

I think somebody on here has a chip with a vit tune for sale.

Whats the rev limit on these cars I have only had the car 3 days and I was thinking it was 6500 but I opend it up today and hit at 7100 I was really suprised. I have to admit I underestomated the zx2 I have had a zx3 and I now also Own an SVTF and I think the zx2 will out run a stock focus zx3.

It will

[turbozetec]

If I go with the S/R ECU is the CWQ3 the best one?

[DOUGIESTYLE]

NGP0 is dyno-proven best, but good luck finding one. They were only in the 99s. There were only 110) 99s produced. IIRC CWQ3 is second, but hardly noticably different.

[mechtech]

If you are going to get programming or a chip, don't bother getting a good computer.
The end result is the same if you have a lousy code or a good one to start with.

[turbozetec]

I think im going to try to have one of my friends at a ford gaurage reflash my compueter to an sr calibration.

[DOUGIESTYLE]

The only SR calibration that Ford service carries is the superceded, dumbed-down, last PCM for SRs. It's only a little better than a stock ZX2 PCM. You'll need a SR VIN to carry-out the process, too.

Do yourself a favor. Invest in a SCT Xcal2 or 3. If you can't afford it, save your money.

How did you come up with CWQ3, anyway? I was under the impression you had one in hand. If not, good luck finding one lol.

[turbozetec]

Searching on here I found that that ecu makes the most hp 146 is what they claim to the crank. I think thats pretty good and I woudnt think that there is alot more to gain out of a custome tune with no mods. Plus I had and preditor with a tune in my svtf and the tune sucked and actually made the car slower then the stock tune.

[mellowness65]

it's all relative to what other mods you have. a computer/tune is only as good as its supporting mods

[DOUGIESTYLE]

I'm pretty sure a Vittune is more aggressive than anything Ford woulda programmed, and with an Xcal, you have the opportunity to re-calibrate with mods as you go. Don't take my word for it tho. :eyes:

BTW NGP0 dyno'd highest peak hp of all the SR PCMs. Like I said tho, it's prolly not available for purchase.

I tell you what, you buy my CWQ3 (that's already SCT tuned by Vit, but will be returned to stock). I'll buy a cheap-ass, stock ZX2 PCM and have Vit re-program my Xcal for it. Will that get you happiness? If so, shoot me an offer.
* The offer is going to hafta compensate for the rarity of my SR PCM, convincing me to sell something I don't really wanna part with, the cost of a replacement PCM, tuning, shipping, and putting up with a hard-headed n00b who doesn't wanna take experienced advice. What's your offer, hotshot?

i have a cwq3, ccrm and ac pressure switch for sale. looking to get 125 for the package. PM me if your interested

Is that the shipped price?

[S/R]

just buy a chip. S/R pcm blow. ZX2fast wifes 98 with a MTA4 and a Diablo is as fast as my C'dub. prolly fast now since he cam'd it

[madness]

So not to beat the dead horse, but I want to make sure I'm clear before I hack this thing up. If I swap my pcm and matching ccrm, will the fan work correctly if I don't want to bother with the a/c switch? My a/c does not work anyway and I'm prolly not gonna fix it anytime soon.

[JonsZX2SR]

NGP0 was also the code used in the PCM sold by Ford performance.

Given that Vit is doing tunes, why not just have him write code for your current PCM code that approximates what he might do for a modified NGP0 or CWQ3 code. In the end what matters is the final tune, not the stock tune nor the 4-character code name.
