This week I installed a thermomaster chip, the 160 degree thermostat AND the 160 degree fan switch on my 84. The easiest part was the chip. Two little bolts and the ecm slid right out. No neck cramps or broken back. I sat/nelt on the ground and it took about 5 or 10 minutes to get it out and back in. The powerstat took a good 10-15 minutes just to get all the crap out of the way to get to the d*mn thing, and the fan switch was a knuckle buster. (hint: you don't have to drain the antifreeze, but it makes it less messy) I think the fan switch it critical and the temp doesn't get much above 165.
Bottom line is that it was ALL worth it. This baby shifts so smoothly when you drive it easy it is like a cady, but when you mat it--hold on. It drops down a couplea gears, presses you into the seat, and winds those gears out like a racecar. I found that it shifts at 4100 and gets 41mph out of 1st, 61mph out of 2nd and 106mph out of 3rd. I'm still working on 4th gear. I also notice that the car is quite a bit quieter. Not a good or bad thing, cause I like the sound, but definately different.
The chip I took out had "delco CDR" on it. Does anybody know if this is an aftermarket chip or stock? Like I said, it made the car louder because it seemed to like 4th gear and it rumbled a lot, also it caused the car to "brake" when you took your foot off the gas. It used to slow down by itself and nearly downshifted with a distinctive "bop, bop bopbop". Now it coasts more.
End of rant...I endorse the change. Lemme know what YOU think.
