catamax944

i forgot about this thread ,i got mine (btw it's race ) and instaled it but couldn't test it because the car is in a milion pieces right now.Only thing i can say is that the engine is smother and the idle dropped from 1000 to 900 ,this with regular gas.

if you order the $109 one for 944 1985.5/1989 which one do they send you? conventional, 3k5...???

catamax944

you can choose one of the 3 ,as long as it's not a dual chip it will cost 100$ +9$ shipping

Indy Rev

Thanks for the info. I was ready to buy one today then I went out and started the Porsche and Knock Knock Knock the engine sounds like an old vw beetle. So new project, find the knock. Im hoping it is just the cheap gas I put in.

Tom - sorry didn't check this thread for a long time til I saw it again. I'm not sure which one I got - but it was just based on the model year of my car, transmission (5spd) and VIN. I got the chip and inserted it myself. Pretty easy - except getting the ECM out of the car can be a bear if you are > 6' tall and have to crawl down into it.

83 944

If you put anything lower than 93 your valves will knock that's your problem. Just learned in my automotive program. And I put in 87 then they started knocking then 91 still knocked and then 93 knock when away

Indy Rev

I'm hoping that's it. I always run 93 and I filled her up on 89 last week for reasons I'm still clueless about. now she has run almost the whole tank and started knocking. I'm gonna refill her today.

Then I'm getting the race chip.

So would one of these chips be a bad idea for me then? I can only get 91 in this area

I just drove 1200 miles over Christmas....had to use 91 octane. I didnt notice any difference...race chip.

Any idea how this wilk chip compares to the 944max?

WizPorsche944

If wonder if it would do anything to help an automatic ?

elzergone

I cant see why it wouldn't help. Its the same engine.

It is interesting to look at the difference between the FRWILK chip and the Promax chip maps for the S2. The Promax adds way more timing to the PT maps, while the FRWILK is more conservative and only adds timing higher in the rev range. At WOT, the FRWILK timing is constant (and has more ignition advance than the Promax) from mid revs all the way to the redline, where as the Promax seems more tailored (ie timing varies with revs). From a casual observation, it appears the Promax has been more tailored to varying loads at WOT.
I haven't run the FRWILK chip, so can't compare real world experience.

so where/when do you specify which chip you want? I can't seem to figure it out.

...Which to go for...3K5 or Race chip...hmmm.... Does the race chip badly hurt fuel economy or only a little?

Porschenthe805

wait so can I run 91 octane with a race chip without knocks? anyone run 91 with there? there is no 93 were i live..
