Arrow PCM Hang

[sadil]

Hey did anyone experience some odd behavior with the ARROW pcm? I installed mine yesterday and it sounds great though I really need to go straight pipe. However, when I stopped at a gas station to record some revs, I felt the engine holding revs as if the throttle was not connected to my pedal. I rev and let go at 4K and it has a delay when coming back down. 1-3k came down normally but anything more than 4K had this odd delay.

I have yet to go to the dealership. CELs came up for a bit but with a few key starts it went away. Now i seem to have inactive CELs stored but no active light.

Hoping a few people can chime in. The car drove flawlessly while I was testing it on the road. The throttle hang while standing still had me scratching my head. Thanks.

There is a throttle relearn that goes along with the install. Must be done at a dealer unfortunately, as they have the necessary computer to do this.

My first thought was throttle relearn too.

Thank you. Looks like I will be scheduling a visit after all...dang it. Any idea of how much I should expect to pay for the re-learn? 1hr labor?

No clue on the cost but Golling should be able to help or directly to Prefix.

This is 100% throttle relearn. Same exact issue happened to me. You have to take it to the dealer they have some tool you can't buy
