Well summertime is coming fast here in az and i notice my car is getting a little hot at lights and sitting in rush hour so i wanted to know if this would be a good buy along with a 160 degree thermostat, Also do you have to get it programmed into the pcm when you have this installed? thanks everyone. Here is the part i am talking about.

The tune can change the temp your fans come on, so if you are thinking about a tune I would just have it tuned to turn on earlier.

 

i don't really have anything that i need to get a tune done for so i was just wondering if i install this would it have to be tuned into the computer. My car is bone stock i have not done anything to it yet.

 

I would use the SLP manual switch if you aren't getting a tune.

yeah i was lookin at that one too but i figured the other one would be easier cause i wouldn't have to remember to turn it off but maybe i will go with that one thanks for your advice

 

you do not have to tune anything for a thermostat however lowering the fan temps is a very useful mod with cooling regardless of which thermo you are running.

 

my fans come on at 192F anyways.... I have a digital gauge(interceptor) and it tells me my temp and they come on at 192f and off around high 180s...
I also have a 160 thermostat

 

I just have a stock thermo right now

 

So for $78 including handling you could turn the fans on early, or for say $150 you can get the software and cable to completely adjust all the tuning in the computer or you could get a cable and mailorder tune. Once you have the cable you can check operation of everything and scan CEL codes so it is something that saves you a fortune in the longrun.

Dyno tuning is overrated.

I understand wiring in a switch to run the fans to cool in the pits but for daily tempature control something like that switch kit is just ignorant. Let the computer do it's thing, if you don't like what it does adjust it don't override it.

 

where do i get this software and cable your talking about?

 

pcmperformance has a nice little compact tidy USB cable, AKMcables are good too but a little more clumsy. $50-65

Software is Tunercat $70 for the program- $20 for the OBD1 LT1 definition file and there is free datalogging software but most of us endup with Datamaster for another $90.

So by the time you get the datalogging stuff it cost over $200 BUT it is some of the best money you can spend if trying to drive and modify a vehicle this old. You can see sensor readings starting to show signs of failure long before it sets a CEL, you can troubleshoot things that don't set a CEL, you can fine tune things.

You could also get email tuning from someone like madz28 for $75 and not have to buy software just the cable, he can change much more than just the fans for you.

The 94-95 LT1 is probably the cheapest/easiest OEM computer system to reprogram and while not perfect is capable of a LOT and very adjustable.
