[scottypimppin]

Even of you could get it (It says its discontinued), it would not work for your car. Its made for a Neon.

I had the same thoughts about getting a MOPAR performance PCM but it simply wont work. Did you fry your original?

 

[scottypimppin]

Yes i fired it so looking for a new one

 

[Bud92gsx]

I don't actually see why you guys are saying it wont work.. A 420a computer is a 420a computer..

Wouldn't it be the same as a talon computer on an eclipse, Or dsmlink vs AEM computer in a dsm..

Besides the fact that it's not made anymore, why would there be a problem?

 

[scottypimppin]

That's what i was thinking

Pin Outs

 

[Bud92gsx]

Pin outs you mean like using a 90 ecu in a difffernt year, or using a different year in a 90? That kind of pin outs where you have to change things around?

 

[scottypimppin]

Well dose anyone know where I can get a PCM other than the dealer?

Yep.

Junkyards, classifieds section, eBay...

 

[scottypimppin]

Well thought of that but the dealer told me that it needs to be tuned for each car that's why they replace them with PCM

Eh? Whoever you spoke to at the dealer may be thinking of the SRT-4 or some of the newer cars with PCM's unique to the car. For those cars it's true that the PCM must be flashed with the car's VIN number.

None of that applies to your car though. Just find a working PCM from another 98 Eclipse RS/GS. Be sure the PCM came from a car with the same transmission as yours too.

 

[scottypimppin]

Ok what do you mean by same tranny as in A/T or the S/N and P/N numbers on the side?

The same transmission... A/T or M/T.

Yes?

[Slo2gen]

Yep, plug and drive, I think it says you must run at least 91 in it though(at least I know you used to when it was made for the 97 only) so if you wanting something to just put cheap gas(is there such a thing anymore?) in and put around in then you might just want to source a used one. If not, then the AFX is a GREAT tool to use if you don't want to use MS! Just plug it in and drive, its self learning!

 

[scottypimppin]

ok thanks guys

Do you run the AFX? I clicked the link and read up on it, but I am wondering how well it performs.

 

[Fotowntalon]

I run it, yes it works extremely well. (do not run with boost) Actual dyno between AFX by itself and AFX comboed with SAFC is about 2whp (thats super accurate for a self tuner). I believe MB saw a 2whp diff as well when he comboed his afx with safc

Thanks for the information Fotowntalon. I might just go that route. How long have you run it and have you ever experienced any issues with it?

 

[Fotowntalon]

Been running it since...wow at least 3 years. As for problems, not sure if you call it a problem, but having to run at least 91 octane can be annoying, also it is annoying anytime your battery dies/is disconnected. Just because it has to relearn the set up and you wont be as good as you could be right away.

That's not too bad. So 91 octane huh? Well I guess that means I would have to run Premium at all times. Yeah, since I now run mid-grade Shell, running high test would bite a little. I will think about it for a little while and make a decision. Thanks for the additional information Fotowntalon.
