Subject: JimC chip: I have been to the mountain top

Dear Jim and fellow Digesters;

BD (Before Digest), I used a stock chip and eventually believed the Dinan marketing BS and got their chip.
For what their chip cost, I thought that there was an improvement. But I had severe pinging over 5500 rpm, ran out of wind over 6000 rpm; even thou I was using the best grade of Mobil/Sunoco/Texaco.

Just because all you Digesters were jumping off the cliff did not mean that I had to.
So I dragged my heals on this JimC chip thing that most Digester rave about.
I perceived that the JimC chip was more radical and assumed more pinging. After all, how could there be that much difference ? WRONG !

I've had a Jim C chip in my 1988 325iX for over a week now and have observed the following:

  • - first time start was a little weird. I assumed that the JimC chip and Mr. Motronics were getting acquainted. (all subsequent starts have been normal)
  • - unbelievable smoothness and seamless power delivery throughout the entire rpm range (almost electric motor / Wankel like)
  • - not one ping anywhere in the rpm range
  • - a feeling of being on-the-cam anywhere in the rpm range
  • - to put it another way: the car has the tiger pacing in a cage and I want to get out feeling
  • - better midrange and top end performance
  • - fuel economy would probably be better, but it is too must fun exercising the rpm range
  • - with restraint, I could use less throttle and get more go
  • - can physically see less throttle in the E30 instantaneous mpg gauge; usually this would be between 20-25 mpg at 70 mph on a smooth interstate, now it is between 25-40 mpg.
  • - I almost want to hunt down and kill me one of those M3 things (slap), sorry, I got carried away..
  • - did I say it has smooth and seemless power ?

Not that it has not already been said: This modification is recommended for one and all.
Next Thursday, I am getting out patient surgery to remove the smile from my face ;-))

Thank You Jim and Thank You fellow Digesters.

Sorry to babble,
Alan Alfano
