If a number of cars (as Mikey states) have this same issue with DHP PCM'*, there may be something to it, and DHP should look into it. If it'* something else, it'* up to each individual owner to find out what it is.

INTENSE PCM'* are designed to run slightly rich at the TOP end as I recall. And for good reason. There is a safety margin with advanced timing, and the fuel has a cooling effect on the cylinder before and during combustion.

From what I hear, the DHP 1.0 is actually programmed to add fuel to lean areas, similar to what Intense does.

If that'* true, Mikey has some issues he should start a new topic for.

In the meantime, I firmly stand by what I stated. The AFC is NOT a performance mod for the topic author, and never will be. It'* not necessary, and it'* not worth the risk even if it was.

If you have an AFC running in your car with a performance PCM, your PCM is ****, or you have other issues.

You can not reliably tune via the narrowband 02 sensor. I don't care what your mods are and what you run 02 mv'* are an indicator only and anyone who tunes based on its numbers will pay either in performance (too rich) or parts (to lean) or maybe even both as the narrowband 02 sensor is wildly inaccurate and becomes more so as it heats up.

As I said before, dynotuning with a wideband and PCM access is the best way to tune the car.

I think that DHP has a little better track record then Intense when it comes to PCM'*. Their is two main reasons for high KR is too much timing and/or to lean. Have you heard of the '04 PCM'*?

oh my....there is no issue with my car'* fuel delivery. my pcm is not ****.....for better information on this topic, perhaps the author or reader should check out clubgp...as they will say as well, a little extra fuel will kill kr

its a well known fact that extra fuel kills kr, but there'* a limit, to much is bad.

its a well known fact that EXTRA fuel kills kr, but there'* a limit, to much is bad.

if my afc failed, id be exactly where i was before it.

there are many ways to kill KR, i could have gotten PEM'*, headers, rockers, cam, intercooler...but for the time being, those are all expensive. another way to kill kr is EXTRA FUEL!!! you dont seem to be understanding this. my car runs perfectly fine without the afc, where it should its not LEAN like its damaging anything, its just that a little more wouldn't hurt anything (within limit) but it does kill KR.


DHP has no problems with there pcm'*, and they were putting out pcm'* well before any other vendor for our cars, DHP has never had problems with pcm'* like other vendors, im not going to turn this into a vendor war they do add fuel to problem areas, among other things

correct me if im wrong, but can you even scan a 95 for kr?

im sure fuel delivery is the same or similiar between intense and dhp pcm'*....there are just a lot more dhp'* out there, probably 9 for every 1 intense....they have been around for longer.

Apparently not, if you listen to what Mikey has to say.

Bonneville PCM'* are NOT the same as GP'*. I'd have to say from my extensive reading on this Forum that nobody has the a reputation as good as INTENSE for Bonneville PCM'*.

Mikey, you're delivering extra fuel with a device that is electronically controlled and powered by electricity. Try it with an adjustable FPR and see what your PCM does with your fuel trims. You might be surprised.

Have you seen the code? fueling tables? timing tables? etc? to make a comment saying that they are different? I'll give you that their Torque MGMT might be different (prolly not) but their timing and fueling no way I don't buy it.

Now that we have established that they are the same look at the track record of DHP PCM'* vs Intense PCM'*. DHP hands down!

As far as the FPR you will bsue pprised and so will your PCM it will be all over the place.

Sorry dubdeuce for this reply... You seem to be on the right track good luck with it.

willwren, there is no problem with dhp. im sure that if i had a intense pcm i would have the same results. the fuel levels were fine, but i dont have enough mods yet for a 3.4 (bought the car with the 3.4, i plan on more mods this month anywyas) so a simple way to get rid of a little knock is just a little more gas then you need, just a little more gas (like 3%) wont hurt your performance, but it will cool the combustion chamber and i know have a safer amount of kr where im not afraid to hit the gas.

the only other way i could have gotten rid of it, was a 3.5" or more mods....im working on the more mods.

Obviously you've tried it as I have? How long have you been running the adjustable FPR? Maybe I'm mistaken, and you actually haven't, so you're not speaking from experience? Last I heard, you haven't run one. Ok. Then you know you're talking out your arse again. Because I've done it. And my fuel trims are perfect, and my PCM isn't confused. For the record, I did alot of homework and asked some prominent experts before trying it. They were all right.

You have NFC what an adjustable FPR will do for you for several reasons. You aren't running a setup that demands as much fuel as mine, and you're not running the same PCM. I fixed my fueling problems perfectly with an adjustable FPR. If fact, I'm the first Gen3 swap to run RIGHT so far that I know of on this Forum.

Mikey, I suggest you fix your KR and fueling through mechanical mods and ditch the AFC as soon as you can afford to.

Let'* get back on topic now. (Blazin, if you want to continue this ridiculous discussion further, dig up the last topic where I discussed it with you and 95naSta and try calling me a liar on my fuel trims again).

This topic is now BACK on topic out of respect to the topic author.
