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
I perceived that the JimC chip was more radical and assumed more pinging.
After all, how could there be that much difference ?
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
- - 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
Thank You Jim and Thank You fellow Digesters.
