would that chip make any kind of difference on a 89 firebird with a 305 TBI that has ngk plugs, 8.5 msd wires, msd blaster coil and cap and rotor and an accel ICM and a K&N air filter and other than that totaly stock?

im just trying to see before i blow 120 on something if it dont do anything

thanks

 

i have been reading different posts and have learned that these suck ***. so if someone will tell me how to delete this post i will

 

I recommend the hypertech thermomaster chip. I have one in my 85 tpi iroc. I have used it for 5 years now and havn't had a problem. I have used it with both the 305 and my 355. It lowers the temp that the fan comes on and gives it a more aggressive spark curve. You'll have to replace your thermostat to a 180 degree one to get the benefits of the new chip. I think there worth it but that's just me and mines tpi also.

 

I'll buy that.....about the thermostat anyway. I noticed it ran alot better with a thermostat at 180 rather then the 165 recommended by Hypertech.

 

would i be able to just put in the termostat with out the thermomaster chip? and how much and where did you get the thermostat?

 

The thermostat runs about 7-10 bux from your local parts store. You can put just the thermostat in but it won't turn the fans on earlier so in traffic it will still run just as hot as it does now. You can hot wire the fans to come on with the key though. I still recommend the chip though.

 

I never thought I would purchase one after reading the boards, but my latest car came with one and a stock chip. I tried it both ways and it has more power with the chip in, and I am checking the gas mileage. It also is the only IROC that I have owned that runs cool, and even did up in the mountains where I crept to 210 every time I drove up the driveway with the previous car. I will post what the mileage difference is. All my cars have been TPI, I don't know if it would work as well on a TBI.

 

oh ok thanks

 

A note on the t-stat: For the TPI engines, from what I've read, the best comprimise is a 170* t-stat. I know of only two places to get one. The dealerships sell AC Delco and TPIS sells one also. From what I understand the TPIS one is just a reboxed Delco. You have to have the p/n when ordering from the dealership. If you ask for a 170* t-stat they'll tell you it doesn't exist 'cause it won't pop up on the computer. The p/n is 10220957. For more info on the coolant system, read the Total Fan Control article found in the tech articles:

buy the thermoaster hypertech chip

 

ok so i am in the process of getting set up for the thermomaster, i just replaced the thermo stat with a 180 degree one and now trying to figure this 180 degree fan switch.

 

just wire you fans to come on when you turn on the ignition,thats how mine is setup and my temp never goes over 200 degress unless im oon the high then it sits at about 215

 

yea thats how my iroc was set up, would i just run the wire from the fan moror strait to the battery?

 

that I couldnt tell you,mine came like that when i bought it,i think its to the red wire inside to the ignition on the fuse box

 

what about the hypertech chip for hp? they say it will add up to 23 hp for stock to mild mods. anybody know? and would you need th programmer as well? is it pre-tuned or could you take to get tuned?

 

send me a link to the one you are looking at, i havent seen it yet.
thanks

 

hyperjunk period. look into some sites that will do custom chip burning. all hyperjunk does it advance the hell out of the timing and make your fans come on sooner. woo.

 

for a stock to lightly modded car.....its worth it rather than getting a custom chip

 

people just need to stop downing chips, NOT everybody has dough just to dish out for some custom chip. Hypertech and JET chips are fine for stock to midly motors, dont worry about custom chips until performance mandates it.
just my 2 cents

 

yea i mean i have never tried one so i would give it a ****. but does anyone have a link to the chip that can supposedly add 20 horsepower??

 

Stop downing chips? Burning my first chip (admittedly, a direct copy of my current chip) cost me less than $100. Last I checked those Hypertech chips clocked in at $250. Who doesn't have the dough now?

 

actually 149 but whos counting, and u didnt include cost for chips or equipment, sure u can make better chips yourself but at least give people the time to learn and grow. DAMN
im not shamin burn u own stuff im just sayin let people make their own decision, isnt this hobby about personalization

 

i didnt know about burning your own chip. what would i need for this. id rather do my own any links?

Plus the DIY prom board and tuning board here. You can pick up a Willem Eeprom programmer off of ebay. Get one that requires external power, the USB port on your compy doesn't provide as much power as is needed most of the time. The eeprom programmer can be as cheap as $20 (What I paid) or as much as $100 (Programs any chip. Ever.) the programmer also allows you to read chips. You can also buy an all-in-one kit from Moates.

A little bit of research here goes a *long* way. Have fun.

this is what i was talking about that adds up 23hp

 

link doesn't go to anything, I wouldn't count on it adding that much hp though.

 

thats the address i copied.when it goes autopartswarehouse.com , its a jet performance chip stage 1, for 82-92 camaros. i got a 1992 3.1. id spend $160 for 7-10 hp.
they also sell the kit with the different chips for different ranges of needs for like $350.
