Hi,i'm new to the game of programming,what is a .bin file?Any good tutorial sites for beginners?

Is speed density harder then MAF tuning,what is the diffrence?

Is there a good datalogging programme available just for LT1?

93's are already SD if i remember correctly, but are chip based rather than flash. Take a look at tunercats for your options...i think theres a site or something like that too which might help out. There are datalogging programs available though im not sure how good they are I've never tuned an obd1 car.

That pretty much covers the same procedure required to tune a '93 LT1 as well. 93 LT1 is chip (EPROM) based, not flash based like 94+. For chip cars, I'd recommend getting a MEMCAL adapter, ZIF socket, and Flash chip from Craig Moates (at ), an inexpensive EPROM programmer (such as the Pocket Programmer from ), and then you could get a cable from either Craig or me (click on my sig pic). ;)

TTS Datamaster (IMO :) ) is the best datalogging program for the LT1. Link is on my web site.

Thanks,i bought from Moates ALDL obd I cable,converterbox and chip burner.
Yes the 93 Lt1 is speed density and has a Chip
Iīm trying to use TunerPro RT but i cant datalogg/emulate just monitor,the programme dosenīt fint the hardware??

I set a few codes:12,13,14,15 and 21,22,23 :),probably best to clear them before going datalogging

I have a PCMforless tune but the car surges and is very rich(prob,ex sensors)
