X-Post - Interest in DIY chip tuning?
#17
Read through the whole 951 thread. This is simply amazing! The work you have done is stunning. And will help the whole community out!
I also am HIGHLY interested in na tuning. Even though I have an 84. Iwould deft upgrade the afm and rme for this ( what late model year dmes are best? I know the 3.1 is he upgraded one)
I've never done tuning before but if you could make a set of baseline maps for the na it would fantastic.
A side note: what causes the 944 stumble. And what fix do the aftermarket chip people make to fix it? This might be good to include in the baselines!
Also i see tuning the na would be easier than turbo. I read about maf kits. But what about injector upgrades and port and polishing? Would those be accessable from the tuning to allow the most benifit.
This tuning could also be amazing for long trips! You could have a seperated tune with retarted timing and slightly leaner af ration as to achieve better mpg.

correct me if im wrong but the 924S was the same as the early 944's i thought....
your right, advance the timing and make it leaner...i was getting a bit drowzy typing all that on the iphone whilest laying in bed at 5am.....damn insomnia!
So for $215 you can get the ostrich and booster from (unless you can fine one used...i saw one on one of these porsche forums for 100$ it was in a MAF posting.)
i think FRWILKS charges 325...so this could potentally a cheaper alternative if you dont mind a little work!
Another Question!!
with this setup...could be upload our current Aftermarket chips profile into the program for review and more baselines/hints?
AND ANOTHER!
i was reading about future timing advance in the 951 forums and you talked about getting a knock sensor/counter. people are saying they hook this into the KLR....the NA doesnt have a KLR so how would you go about hooking it up...its need the input right....
then again do NA need the knock sensor sense we are not boosting...i would think that would only be needed in Turbo/SC

OK...maybe I'm dumb (NOT trying to be a dick).... but what is the purpose for an NA car?
I mean, there is really no need for us to tune our cars more than once, as we can't vary boost levels, add innercoolers, or anything else. Any upgrades we do (cam, port and polish) are extremely expensive (compared to the rest of the cars value) and will see little gains anyway.
Wouldn't it be cheaper and easier for us to buy a good chip and be done? Russell Berry has even said that if we do make changes to our engines, he would re-burn his chip to match.
For a turbo ride.... this is fantastic, but for an NA, I just can see buying all the equipment to do this.

Because if you do happen to do those upgrades on the NA then something like this is a godsend.
Rogue, i have an 87 DME with an autothority next time theres a meet i can bring it if you want to rip the chip.
I'm interested! I have a stock 88 dme in the car right now but i was curious as to the difference between the maps and such (as in what the hell does that autothority do besides raise the rev limit...)
What about 16v cars? dads got an S2 with a 968 motor and is thinking about supercharging it....

the point of it on NA's is for allowing for modifications to be done!
but it also its an opening for SMALL Supercharger Projects...(5psi or so is what the DME can handle)
if you wanted a small m42 or such with larger injectors, different headers, ICer, possible homebrew Maf, porting and polishing (some people with shops can do this themselves...lucky people).
also as i said you could have multiple profiles! 1 for long road trips maximizing MPG, 1 for track/autocross, one for street that doesn't eat gas horribly.
i could also see Porsche-files using this on kids cars for autocrosses and such as you could limit with DME i believe like a governor.
on top of all this, learning to tune a car correctly and efficiently is supposed to be a very useful and enlightening skill to have. this can transfer over to many other cars. also knowing how your cars runs and how the DME affects it all, cause and effect, helps everyone to understand the inner workings of the car actually work!

And I agree with both of you 100%....
The only thing that make it iffy for me is, you're talking about 2-3hp or 2-3mpg. The NA engine just doesn't improve enough with ANY mod to make it worth the money and effort.
Plus, Russell Berry (MaxHP) makes a fantastic NA chip (which I have). He's said that if any modifications are done to your car, and you already own his chip, he will re-burn it for you to correct for the mods.
I can't compete with that. (I'm talking about an NA car here .... if your adding a supercharger, then its no longer NA, and correcting the tune would be beneficial)

Last time I check the RB's chip was ~$200. I guess this simply comes down to if you want to be able to tune in real-time, learn the inner workings of your car, and have the ability to adjust for potential upgrades...

The 16v cars are on the "to-do" list. But I don't plan on having anything out for them before the end of the year...

All the equipment...? It is a simple emulator <$200, and free software...

I just reread my posts, and I apologize if I was sounding pessimistic. I just think that spending time and money on improving the NA engine is all in vane. You could spend thousands of dollars and make 30 more HP. (I know you system is less than $200, but its still only 2-3hp in an NA car)
However, for a turbo car, this is brilliant (I've said my piece .... I shall interrupt no more!)
