Thank you for the explanation.

Understood on the the kit for the S & S2 being in the pipeline. I'll be keeping an eye on your website for updates!

Just a quick update to say that the 944NA MAF kit is done, and I've turned on ordering on the website!

Rogue Tuning - Home

Just out of curiosity:
would this also install on a no cat/no O2 sensor '85/2 NA euro model? Or would you need the O2 sensor input too?
second question: what kind of gains can one expect with just the offset cam key (and no MAF conv)? I know it's more of a shift in power band but I'm just curious what it would do for mid-top end on an otherwise standard engine.

It's a cool product you are selling!

Yes, this will work just fine on a no cat / no O2 sensor model.

The offset cam key should make around 4-5% better hp/tq everywhere under 5500rpm. And it will probably make slightly more peak power than stock, though at about 500rpm sooner than factory.

Added this to my Christmas list :D

So, as a newbie just to trying to Summarize what is above and on the web site: a bone-stock '89 with 2.7L engine would not require the MAP sensor (that's for turbo); a cat-back exhaust equivalent to a standard turbo exhaust (2.5" with oem cat with freer-flowing resonator); and the NA-Tune kit. How well would this work with the stock exhaust (that I just replaced).

John,
You are correct that your car does not require a MAP sensor (nor does the NA-Tune kit use a MAP sensor regardless). The no-cat & cat-back exhaust did very little to gain any power, I would say it was worth only 1-3rwhp. It does sound good, but didn't make any real power change.

The NA-Tune is all that is required to convert to MAF. It comes with the bolt-in MAF sensor (bolts right in-place of the AFM); the plug-n-play wiring which plugs right into the factory AFM plug (one additional wire needs to go to switched +12v); and the new chip for the DME to understand the MAF sensor properly.

Just curious, has anyone installed this setup and done a smog test in CA? Also, any reviews from actual users yet?

Here is a link to a review of the na-tune

If I had the extra cash I would have bought one by now.

hey joshua...

i wonder, did you also do a dyno runs for the other combinations of the offset key? the package comes with a 2degree so right? how did -2deg, +2deg perform? or maybe +5deg (1 cam gear tooth - 4deg offset) ? or maybe even +7deg?

I did try a -4° run, and though it did hold power in the upper RPMs better, the overall power & torque was quite a bit lower compared to the +4° run:

Has anybody found the supplied chip is different from that shown on the site? I don't see the orientation required in the directions.

?
This is the correct orientation:

If there is any doubt, you can rub your fingernail along the edge to identify where the 'notch' in the chip is.

Thanks.

I think I did this right. I did not get what appear to be the smaller extenders for the socket. I assumed I had to remove the socket and solder the chip/board combo where the socket was. Did I do the right thing?

I need to post a picture tomorrow since I have a few pins that are bridged by solder, but maybe they are supposed to be.

I am disappointed by the lack of specific instructions for this.

Art, I am sorry for the lack of specific instructions regarding the chip installation...
There is no soldering that needs to be done (assuming you have a 28pin DME). All that needs to be done is remove the old chip, and plug in the new one...

If you have the 24pin DME then you need to convert it to 28pin by installing the extra 4 pins, and installing a jumper. As I mention on my website, all of my Tunes require a 28pin DME.

I do go over the conversion process on my website here:

And I also offer the conversion service; but if you want to do it yourself, I can supply you the necessary pins and jumper - you just have to let me know that you need them!

I couldn't find the notch in the chip when I first got my kit either. Make sure you don't stupidly install it backwards like I did. Ever since I installed it backwards my car won't run right/at all :mad:

Installing the chip backwards should not hurt it... Regardless, you can send me back your old chip and I'll replace it.

Will do.

To anyone that buys this kit: Do NOT hook it up to the side of the coil with the green wire. Connect it to the battery if you want to "test it out", then find a switched 12 volts from somewhere else when you install it permanently. You will fry the sensor if you connect it to the side of the coil with the green wire like my stupid ass did.

I suggest making a tutorial video!

If I spend that much money I sure as hell don't want to hook it up wrong. haha
