I installed FR Wilk's Power Prom 2 today.
I must say, after being somewhat skeptical based on the performance of past chips from other distributors, I am truly impressed.
Specifics:
Installation was a snap on a series 2 car, taking no more than 15 minutes. The only difference in installation between FR's chip and others is the addition of the jumper wire that connects to the harness which connects where the altitude switch used to plug into. By virtue of removing the jumper and reconnecting the altitude switch, the car reverts back to the factory fuel map. This is a welcome addition to those that live in states that have smog tests.
Installed vehicle: 1985.5 944 NA, 118K miles, manual transmission with limited slip differential.
Performance:
Performance was stunning. One of the problems with aftermarket chips is that they are normally a bit of a comprimise, sacrificing drivability for performance. The downside to this is, the dynamics of the vehicle change. stumbling, and flat spots in various places in the power curve are common. Additionally, most aftermarket chips have a requirement for higher octane fuel.
This is NOT the case with FR's chip.
What FR's chip seems to do, is spread out the power curve.
The car pulled effortlessly across the entire RPM range.
That "kick" you normally feel at around 3500 and the flat spot that creeps in above 5500 is GONE.
Also gone is the feeling that you've "hit the wall" and that you need to "push" through it with more throttle.
In practical numbers, from a standing start (0 MPH\approx 950 RPM),
Weather conditions: Rain, 65 deg F
Shift from 1st to 2nd: approx 6000 RPM, 37MPH
Shift from 2nd to 3rd: approx 5700 RPM, 62MPH
Shift from 3rd to 4th: Approx 6000 RPM, 82 MPH
Shift from 4th to 5th: Approx 4000 RPM, 95 MPH
Unable to test at higher speeds due to traffic on the freeway and degrading weather conditions.....
This is a distince improvement
Of note, I did not hit the rev limiter at any time. I kept my shifts conservative, as I generally do not like to shift above 6000. I did however feel that I could have gotten more speed if I had taken the car up to 6500. The 1st, 2nd, and 3rd gear performance was impressive. Usually in a 944, it is difficult to get the car above 30MPH in 1st gear without hitting the rev limiter.
Will post better numbers later this week when is is nice and dry. Also, if it is available, will run a dyno between FR's chip and the stock configuration.
Bravo FR!
