This program allows full programming modifications of the stock computer. It allows you to change fueling, spark, shift points etc. Ive been programming TBI trucks for a while now but these have a removable eprom in them which you "burn" the file to. With OBD2 there is a flash programmable chip which is not removed but up till now there were no programs that could edit the vortec truck pcms and only a few shops in the country could do the reprogram

 

funny you ask, i was just looking at that software myself

 

I use that and HP Tuners regularly. Both work very well.

 

The only down side to their software is they don't have a scanner. They have been promising one for about a year and a half now, but I haven't head anything new on it in a long time.

 

I've got a good friend who uses it, happens to be the same guy tuning my truck with it.

 

you should ask charlie to go with you to the track and maybe do some fine tuning.

 

EFI live has a "built in" scanner doesnt it? would it still be cheaper to buy TunerCat and then a scanner... than EFI live?
just like everybody else i want some software, but i want the cheapest also...

Thanks guys!

 

I have Tunercat and love it.I also have HPTuners,both are nice software but Tunercat is suppost to come out with MXscan,I am waiting for that as many others are.All in all tunercat is not expensive at all and it is nice.

 

I also use Tunercat, it has been on the market for 15 months now. I like teh licensing which is $79.00 for unlimited vehicles thatare supported by the definition file you choose.
I have a 1997 Vortec 350 rcsb truck, so I boughtthe definition file that covers the 96-97 trucks. I can tune any 4.3, 5.0, 5.7 or 454 that I can find.

MXScan is a scanner/logger that has biderectional control and supports wideband O2 sensor inputs. The reason MXScan has been delayed, is because the developer has gone back to support the arly 96-97 Vortec trucks. Tunercats is the only software that supports the 96-2000 Vortec 350, 305, and 454. James didnt want to leave us early Voretc truck owners in the lurch.
If he went ahead and cut us GEN 1-E Vortec owners out, and simply supported teh GEN 2 and GEN 3 GM guys, MXScan would have been out months ago.

I like Tunercats myself, there is a lot of tables that can be changed.Even if you cant the a/f ratios right now, its way worth the money to be able to remove Torque3 management, change shift points, set for gears, increase shift firmness, raise top speed limiter to 255mph, shorten shift timing etc etc.
there is no need to buy a Hypertech when there is Tunercats OBD2.

Just 2 days ago anther update was released. It takes me 50 seconds to download the update,then 5 seconds to install it. Good support.

When MXScan is released Tunercats will be the ONLY complete tuning suite for the 1996-2000 GEN 1-E Vortec trucks. Al the others support the new trucks only.

you can change the w.o.t. a/f ratio, what more would you want to change?
