Choices of Performance computers for 95-99 Neons

birky15b · **Joined:** Sun May 21, 2006 6:48 pm **Posts:** 1

what kind of computers can I find for my neon and what brand will give the best performance and price? Does anybody have a 5 speed 1st gen for sale DOHC or SOHC? thanx alot :?:

You basically have two choices -- the Mopar Performance one, or the AF/X one from Howell Automotive. No one else has cracked the Neon CPU code, so there are no other aftermarket alternatives. The only other options are complete stand-alone systems, but those are pretty hard-core for the average modder.

that is not exactly right...

We cracked the computer here in Bogotá, Colombia... my stock PCM has a soldered socket in which you can put different kind of optimized chips

there was a big post about this long ago but it was erased dont know why

Bogota doesn't really play in the big picture though since it's pretty much NOT going to happen here in the states. Chuck's post covers the options here.

but its another option..
it can be shipped and maybe cheaper than modern performance...

'Maybe' - but the Shipping and Tarriffs, etc., shipping to and from Columbia would probably kill you.

i dont understand how there would be tarrifs on a computer you already own shipped somewhere. it would be like shipping a gift to someone, if the return sender that did the work sent it back the same way. did the same thing from the states to canada, only with something else, and i didn't have to pay duties. but it will be more of a hassle to send your computer away and wait for a while to get it back, then order one while you drive on yours.

Then go ahead and do it. Be sure to let us all know how it works including dyno before and after.

that is right...

but he says clearly "no one else has cracked the Neon CPU"

and yes... somebody else has cracked the neon CPU... far away from the US but it has been cracked...

and yes I know im too far away to make it viable for you US guys... BTW... I have a new cam in transit so im going to reprogram my PCM... ill take pictures so that you can guys see how is the process...

Another problem for you US guys is that I "think" my PCM is not completely legal for your laws... for example I guess chrysler corp has some copyright issues for reverse engineering in their computers (im just guessing though) and you guys as far as I know have very strict emission and testing laws (which are practically nonexistant here) and I dont know if my chips pass those tests...

I know Jet chips are junk (or used to be) I heard that they have been greatly improved, but dont know.

Actually there are numerous people in the US that can do it. They just aren't in the business of modifying the code, flashing it into various PCMs and then selling them. For almost 100% of the people in North America that want a performance PCM, Mopar Performance and AFX are the only logical choices.

i have a mopar pcm for sale for a 97-99 sohc 5 speed.

I hope your not thinking of putting in a Dohc computer in your sohc.

When I did the other day, testing out that part, and a bunch of other parts, the Dohc computer ran excessively rich, making the car lose 5 hp over the stock sohc computer ! Thats even with my modifications !

neon915 · **Posted:** Sun May 28, 2006 10:31 am

no i was thinking stocker computer. if i get what i want for the computer i well sell it sence the car well be turbo soon anuff. and could save on a little gas.

true again

in fact... the "company" that cracked my PCM claims to have some kind of business in the US

What kind of Horsepower gains can you expect out of a mopar or AF/X performance chip?

People get shipments from bogata all the time ....

yes... the post was deleted...

I figured that out one day I was checking my own posts and that one was not in the list... there are other posts linking to that one and it wont work either... so yes it was deleted

Just for clarification, they're not chips, they are replacement PCM's.
There really is no hard number for the increased horsepower or torque as these PCM's will adapt to any modifications and the more modifications you make, the greater your power gains.
The AF/X race will give you the greatest gains but it is also the priciest. The Mopar and the AF/X street are virtually identical ( I recall that the AF/X reportedly made an extra 1 or 2 hp over the Mopar unit ).

I've *heard* upwards of 5 hp for the AF/X over the MP.

These computers from Mopar Performance that aggressively advance the timing, and fuel curves of your Neon to give more power and torque.
These give 8-11 hp at the wheels (Depending on modifications) and are available for manual transmission Neon's only.

These will also increase the rev limiter to 7400 on the Sohc and 7600 rpm on the Dohc.

The post was not intentionally deleted, it was dumped during a purge. If you wanted to submit the pictures and information again I will make sure it makes it to the archives.

Also, programming to your computer would not be suitable for use in in North America due to different altitudes and climates. What works for you there will not necessary work here.

Even with the Mopar PCM I have heard troubles with pinging and power loss driving between Edmonton and Vancouver just because of the altitude differences.

There are many factors that need to be subjected to scruntiny.

Can you provide the information you had before, you said you had some different modes and what not.

PoweRJoshE · **Posted:** Tue May 30, 2006 12:35 am

Yes...

As you can see... the chip sits on a socket which was soldered in the place where the old chip was... With a special tool you can remove the chip from the socket and change the chip...

I have many chips lying around and I swap them whenever I need something special (and im not lazy, since as you can figure it out, removing the PCM, although easy, takes time) for example I have:

-1/4 mile chip
-Economy chip
-Stock chip
-86 octane chip

I have done like 10 different programs for the car... and they do work... for example the economy chip really increases my gas mileage but if I race with that chip... my times increase like a second and a half compared with the 1/4 mile chip...

and now Im programming a new chip because I ported my head and Im installing a new cam (magnum) so maybe I can take advantage of it with a new program...

Senor Bogatata, Input, Johnny 5 need input .... '95s have no friggin' AFX available.

And according to my time-slips the SOHC and DOHC Mopar performance ECU's make no difference to either my DSP rule book engined "Greon" or my "ITA" rule book engined "Bluon" at Ennis drag strip. Both are SOHC's.

Boost Junkie was there (at Ennis)and tire pressures made more difference than the ECU did. Both engines have stock intakes (yeah I know a "real DSP" car should have a modified intake but I did change the throttle body so neah). Cold airs and Headers. And yes, I did put a real drag racer in my car to see how far off I was.

You know if I wasn't so *a#S!d^f* at myself for not getting the drag DOHC'er built I might show up on N2k6 Friday drags just to put that "the SOHC MP ECU is always better than the DOHC MP ECU on every SOHC Neon" in some more realistic light.

Now on the Autocross course I like the extra 200 RPM of the DOHC ECU. I haven't seen a difference one way or another other than 1 less shift wins the day. I've heard others say the DOHC ECU was faster in the SOHC and I was like no way, that's not what the .org said. So I beat myself to death trying them both. I now like the DOHC MP ECU too. I'm not calling who ever did the Dyno a lier. There may have been some "gain" on a curve somewhere. Hell, I've dyno'ed my cars and seen more than 2Hp difference based on Time of day. I've yet to see that translate to a noticeable time difference on either sport.

I know some STS Honda guys have like 5 chips. They usually just stick with their favorite one. But *a#S!d^f* they drive Honda's, superstition helps those guys.

id like to add that the afx at least in central pennsylvannia with thealtitude and temperature is actual set up for 98octane insted of the advertised 93, if i put a set of plugs in itd fry them from all the timing, ive since been making more streetable power with a stock pcm till i get a mopar.

Plugs fry from timing???

And the higher the altitude, the lower the octane required.
