Subject: RE: eta Conforti chip
Ray and others with eta engines,
I installed a Jim Conforti EPROM from Mesa last week in my 325es, along
with a K&N filter. Here are my impressions:
- no effect on idle
- startoff in first gear is normal (i.e. unchanged) until about 3000 rpm,
and then the car takes off with a whoosh not unlike a mild turbo boost
- second gear is very strong and third gear now feels like second
- massive pulling power up hills in fourth and even fifth gear, with
occasional ping at pedal-to-the-floorboards up a steep hill (I'm using
Shell 93 Supreme)
- engine is extremely willing to rev, right up past 5000 rpm, where our
tachometer stops (i.e. you can "pin" the tach before you hit the rev
limiter)
- fuel economy is unchanged, except you can get better fuel economy at
higher highway speeds than before, probably due to the increased
power output (I've driven the car 1500 miles since last
Thursday when I installed it, including a 1000 mile trip from
Massachusetts to Indiana, where I averaged 28.3 mpg at a sustained
75+ mph for 15 hours)
- I would estimate (butt-dyno only) that the engine is now putting out
about 20% more horsepower and torque, which would mean about 140hp and
around 200 lbs/ft of torque
- the K&N filter makes the engine sound very snarly at high rpms - a very
cool sound
- in general, the car is MUCH more fun, especially around town
The Conforti chip took two weeks to get from Mesa to me in Massachusetts,
but since I opted for UCS Ground shipping, one week of that was just getting
the package from Newport Beach, CA where Mesa is to me in Massachusetts.
I'm very satisfied with the chip. I'm concerned with engine longevity now
that I'm driving it a bit harder, but that's a risk I know I'm taking
that's nobody's fault but my own (Jim DOES have all those disclaimers for
a reason).
Thank you Jim Conforti and thank you Mesa Performance!
