You can see my mods in my signature.
I know speed density supposedly throws everything out the window at WOT and thats what I'm worried about.

Are there any speed density owners on this board that have noticed a nice increase with a certain brand custom chip?
thanks

If you're running the same cam and heads, you dont need a custom chip.

My car with ZZ4 cam and ported L98 heads used the stock 305 5-speed chip.

Speed density needing a chip after every mod is a rumor started by the MAF guys.

Why don't you burn your own chip? I've been boning up on all the posts on the PROM Board (start from the oldest post and work backwards) and you'll quickly learn the various equipment and software you'll need to burn your own chips.

Start with Traxion's article on PROM burning. It has excellent information to get you started with useful links. Between Traxion's article, the links he provided and reading the PROM Board posts from the oldest to the most recent, I have almost EVERY QUESTION I can think of already answered.

The only thing left for me to do is actually get the equipment (it's just been ordered for my Christmas present) and start "playing". I can honestly say that the equipment to do that is not that much, far cheaper than a custom chip. And that is even for this Canadian that has to have everything shipped via a Custom Broker and pay a variety of taxes to get the equipment into the country.

Will a custom chip help on a stock or mildly modded engine? Yes. Will it help a lot? Depends on how well you optimize but don't expect .5-1 second on a stock/mildly modded engine. But you will learn a lot and when it does come to more serious mods, you'll know exactly what to do so you can get the FULL POTENTIAL of all those new parts.

Besides, it is easier to learn on a stock/mildly modded engine as your stock PROM is still able to work (won't get stranded) and you can compare the results of your changes for further knowledge (and hopefully performance). I would HATE to have to learn how to burn a PROM on an engine I just seriously modded and I cannot get the car to run right without having a custom PROM burnt to at least allow me to drive the car.

Lastly, Kevin is quite correct about how "forgiving" the SD cars really are. Yes, they can always perform better if optimized, but do perform quite well with minor mods with just the stock PROM.

See you at the PROM board.

 

Thanks guys.

Glenn, what is knowledge is needed for burning chips? Intengers? Equations? Thats what I was afraid of :B

I dont want to buy the software and be dumbfounded.

Let me know bro

The actual mechanics of modifying the "bin", and burning the chip is easy (from what I read from the archives and PROM board). You can learn ALL OF THAT in probably a good half day of research through the archives...starting with Traxion's excellent article on PROM burning in the archives.

You can quickly learn how to add/subtract fuel and spark, but getting the right results involves a LOT OF EXPERIMENTATION.

No magic formulas (if it was that easy EVERYONE would do it and custom chips wouldn't cost so much). Just a lot of experimentation. It's part science but its also a heck of a lot of art (and patience).

I don't know if it is either a artful science or a scientific art. I lean towards a scientific art.
