What's the advantage? Thinking about doing this if I can gain some numbers. On a 93 though how would you accomplish this? Do you need an assortment of chips with different "recipies" or what?

 

Why do you think you need to dyno tune your car with your current mods?

Dynotuning on a 93 isn't done by many just because most shops aren't set up to burn chips.

It's pretty much the same thing as you would dyno tune a 94+ car except you have to burn chips after each run instead of reprogramming through the data port.

 

Car is up for winter mods...installing LT4 hotcam kit, having some head work done, increasing injector size and insalling a NX wet kit. So when I'm through I thought I could use a tune. So basically what your saying is that I call someone like PCMforless and tell them my mods...they burn a chip for a price...and thats as much as I can do?

 

I agree with madwolf, most shops don't dynotune a speed density car because of the hassle of actually doing it. One of the problems is the lack of an on-the-fly tuning system, the other is the extra equipment needed to burn the chips. I've been searching within 2-3 hours of me here in NJ and even SLP doesn't dyno tune SD cars.

 

It's a pain to do, to say the least. There is a new option out there, however, with Tunercat's ROMulator program for EPROM cars. However, it is rather expensive and I doubt you will find a dyno tuner that has the equipment. If you buy the stuff yourself and take it to the dyno, I'm sure they'd be more than happy to put your car up on the dyno and let you make the adjustments. Course, you are going to spend at least $500 for everything you need just to use the ROMulator and then probably something along the lines of $100 to $250 an hour on the dyno. Not exactly cost effective, if you ask me.

 

I was asking the chip guy at pcmforless about this, and he said he's tried and it doesn't work with our cars.

Best bet would be to buy a programmer, a few amtel 29C256 flash chips, and all necessary cables and logging/scanning software and learn to tune it yourself.

 

Perhaps they were using the ROMulator 1 rather than the ROMulator 2. The original ROMulator did not support EPROMs over 256K, which the 93 LT1 F-body has a 512K EPROM. However, the ROMulator 2 does support 512K EPROMs. The only type of GM PCM that the ROMulator 2 with RT tuner will not work on are FLASH PCMs.

 

The 93 has a 256K eprom.

whatsup,
I'm in the midwest and I can tune 93s if you ever need some help with that.
