View Full Version : 1992 Chevrolet Fullsize Blazer Tuning/Chip Help?
05-20-2011, 07:59 PM
I am building a 1992 Fullsize Blazer, and I need help with a custom tune. Can anyone point me in the right direction? I have been doing some reading, but only found TBIchips to tune the OBS trucks. Can anyone tell me if TBIchips is reliable or if they have a good reputation? Are their anyother companies I can use for a custom tune? Any input would be greatly appreciated.

I used TBI chips. Brian is a great guy & will help you any way he can. But it is hard to tune anything properly through the mail. Even with data logging it is still hard if not impossable to get a tune spot on. I think if you have a mildly modified engine he can help you alot. But if you have alot of mods then he will never get it right & you will never relieze you engine true potential. I have a 383 with vortec heads, roller cam, 454 throttle body & after 19 chips I gave up. I'm not driving the truck while I'm saving money for a powerjection fuel injection system. If I would have done this when I built the engine I would have over $400 for this upgrade.

Transplant, can you explain what a powerjection fuel injection system is and the benefits? Thanks.

It is a self tuning fuel injection system. It is similar to the fast efi system but you can have up to 25 lbs of boost & use nitrous. You can find info here http://www.professional-products.com/EFI_3.php

Why not buy a programmer, ALDL cable an some chips to do your own programming?

I just don't have the time for the learning curve. Woking 2 jobs & going to school. I'm changing the cam & adding nitrous at a later date. I can change the cam 10 times & not have to burn 100 chips. This is my best option.

Six_Shooter, I would like to go that route, but have no idea where to begin with what I will be reading, what needs to be changed when programming, and where to change it to. Is it extremely hard?

It seems daunting at first, but gets easier the more you do it.

Six_Shooter, thanks for all the information. Can I ask if you are on Eagle-mark.com? If so, great info also. I have been doing a lot of reading and I read about EPROM Emulators. Can these provide benefits and could one be used on my 1992 Chevrolet? It seems tuning in real time would be more practical, and much faster than burning chips? Can I ask you opinion on this?

Yes, I go by the same name there.
Yes, the emulator reduces the time spent tuning by a large amount.
Yes, they can be used on a 1992 Chevy truck.

Have you looked into the Dynamic EFI.

Seaeagle2, no I have not looked into this. Can you explain to me what it is and the tuning that is involved in it? Thanks.
