I have a 95 neon with a SOHC engine. How do I get rid of the speed limiter.

Buy a 95 ACR PCM (no speed limiter) or unplug the speed sensor (but then you can't tell how fast you are going).

what are the numbers on an acr computer. On the car or the unit.

Actually the MOPAR PCM limits at 148 MPH, the ACR/RT PCM limits at 130 MPH, and the AF/X PCM has no limit. Stock PCM is limited to 118 MPH.

What are the numbers for a AF/X pcm. Where can I get a mopor pcm.

The MOAPR performance PCM MAY still be abvailiable from a dealer, if not then try Neons.org, Modern Performance, EBay. The AF/X came in two versions, street and strip with the strip version offering a bit more power, the down side was you had to provide them with your PCM in oder to buy theirs. I will dig some data on on these two products and post tomorrow.

I do not have figures for the SOHC, but for the DOHC, the MOPAR PCM produces 138.6 HP@6500 RPM/the AF/X street 141.8@6500 nd the stock ACR 131.2@7000 RPM (these are dynomometer readings), do not confuse them with the sales literature readings as these compensate for any power loss through the clutch and drive axles). Best 1/4 mile readings were:
Stock ACR=15.21@92.11 MPH
MOPAR =15.04@93.33
AF/X=14.93@93.81.

You can buy these products at howellautomtive, modernperformance, maybe EBay and you might find a used one at neons.org.

Good luck

thank you very much.
