Hey guys, I have a question about the AF/X computer. I have a 99 Eclipse GS and I want a racing computer that will really work. I have heard nothing but good things about the AF/X computer. I was looking on Howell.com and they have AF/X computers for every year of neon. Will the AF/X computer from the 97-99 420a neon would work on my 99 eclipse? It looks almost identical to mine, but I heard that every other year of eclipse has different plugs for the computer wires. Thanks.

Can you handle the power of my GS?

wrong section. and no they will not not work. only the 97 eclipse one will work. i think someone tried it on a 98 or 99 but not sure of the results. the neon will not work. they are not interchangable.

USED TO HAVE...Everything you wish you had, and then some...

You are somebody special Tim, you matter! - from the admins (but nobody likes you, because your username is just like that other guy's, and you whine a lot)

Programming remains the same throughout the years (minus some weirdness in some 95 models) as does the colors of the wires in your ECU harness. The only thing that changed were the pin numbers themselves.

the deal is, every pinout from 95-98 is different from the rest. the only consecutive year that the ecu's were the same were 98 and 99. the rest had slight differences. why they only have one for the 97 eclipse right now (and thats MT mind you) i dont know. but no, the neon ecu's wont work.

if the 98 and 99 were the same, then why didnt they just make the af/x ecu for those 2 years instead of limiting it to just one year? that doesnt make any sense to me...

Becuase their test ECU they reverse engineered was off of a 97. Only a guess.

To clear some mis information up. The 95 computer is very different, not even close to working.

The 96-99 all have same harness. The only differences are minor pin differences. I plugged a stock 97 ecu into my 96 car and it ran with no problems. i then sent that 97 ecu to howell had the afx program put on it ($490) and plugged the reprogrammed ecu into my car, it ran fine.

The AFX ECU cost $540 without core trade in. It cost Howell about $3.00 to make the ECU. YES THAT IS $3.00. All they do is replace the crystal for one with a higher frequency. This raises the revlimiter to 7800, leans the fuel some, and advances the timing some.

If you had the '97 ecu, would it be possible to change the pin-outs any way.

I'm sure they had to pay a couple bucks for the R&D to go into that ecu as well.

yeah maybe 3 dollars in physical parts but you forget the R&D time put into that. and also overhead/the machine to burn the program into the chip,etc.. its not like their making this for a honda where they will sell hunderds of these.

Just so everyone knows for a 96-99 (not 97 obviously)vehical all you have to do is rewire the harness to work. there are some minor differences between each but the wire colors are the same
just rewire the harness to matchup the wire colors, thats it you dont even need the schematic.

Or id just get a megasquirt and have full control over whatever you want

I didnt have to rewire nothing on my 96. There arent any burnt chips, no rom tunning machines, nothing. It takes 10 seconds to pull the crystal out and stick another one in. Now getting around that protective gel probably takes a while.

I edited to the wiki!

Remove, replace with a different frequency.

This is a common mod in turbo charged nissan's. Nissan doesnt use speed density programs so this will actually lower there timing a bit, allowing for more boost.

This reminds me when I was told I was bullshit when I said I put a AFX ECU on my 96 talon. Having a degree in electrical engineering kinda helps too.

OOH someone just got owned i just dont know who yet.

ok, at least that last response was better than just a plain "You're bullshit, because I said so"

Thanks for telling us why.

I mentioned earlier than getting around the protective gel is hard, so the pic I posted OBVIOUSLY isnt a 2gnt ecu. It is a FWD Sr20 ecu NO GEL. I know 2gnt are map based, who doesnt. I sold my afx ecu for almost what I paid for it. replaced the crystal in my stock and got the same affects.

is there any way you can prove that?

im not trying to be a dick but im interested... im just wondering if what your saying is really true. can you get us pictures of yours?

It's sad to see that it's gone this far.

aww man. i needed a good laugh. i threw 30 crystals in my ecu. and gained 30 hp. it was crazy. one of them was a 3* timing at wot crystal. and another was +10psi super turbo power crystal

stock speed 8.000002 replaced with 8.440

8.440/8 = 1.055

7250(stock revlimit) X 1.055 = 7648.75 (new rev limit)
The stock tach is off some, so it seems like 7700-7800.

I tried a 8.860 crystal this threw things off alot. The car didnt run good, i dont know if it was detonation or misfires (AFX may know the fix to this). All the crystal does is trick the ecu into thinking it is alot a lower rpm than it really is. The idle speed is raised, revlimiter raised, speed gov (if we had one) would be raised. Ignition maps, and fuel maps would be off some.

The way chrysler and nissan calculates things are way different. Nissan basically uses the same program for all their cars, but uses different correction factors for each motor. I was able to get Nissan's program from the dump port on the ecu. Chrysler doesnt have this.

I sold that ECU and my car some months go, it proved to be unreliable (the drivetrain not the ecu).

I didnt post this to bash AFX, they obviously have the pcm software, i dont.

But on another note:

I didnt post this to get called a liar and "owned" (<---that shit is old, let it go). This is one of the reasons I left the 2gnt community and went back to my favorite cars (Nissan). This community is too closed minded, any type of change and be prepared to get flamed. Do a search on outlaw engineering, they were ready to make some gaskets for us, but no i got flamed for bringing it up. funny thing is they just came out with some gaskets for the SR20VE (which is a rare motor, very few in the US) it gained 10hp at the wheels.

And besides the 2gnt is heavy and has ugly gearing making it slow, unless u are turbocharged, and then u better have that bottom end built or it will blow around 10psi. and since it is map based, be ready to run like 3-4 piggy back systems. I aint knocking a turbocharged 2gnt, but it just had too many if and or buts when it came to running boost.

I had my NA 2gnt heavily modified. head work, cams, bolt ons, lsd, afx ecu and it still was slow. with the wind to its back it might have ran a 14.9. But the car I got now with a sr20ve swap will run circles around any NA 2gnt and will probably stick with or beat any modified 4g63 with a stock turbo (cant hang with the big boys.....yet.

sorry about the rant, but i am sure others feel this way.

10whp from a gasket.....

Not to change conversation, but I have an AFX Race unit ECU for sale for $330 over in the sale/wanted section. Oh yeah, I taped one of those gaskets on my hood and it was more like 9 Hp, I wouldn't go as far as to say 10hp, I'll have to dyno the car to see.
