ok i will soon be gettting a whole 95 z28 rear end with posi and 3.42's i will have to have my spedo and my shift points fixed..... what can i do...... someone said hypertech........ but they make them for 94 3.4's????

 

they MADE them..key word being MADE them...they dont make them no more and i have contacted them and have no intention of making them again....we are out of luck....i need one too...i put 3.73 gears..and 17's...so i need to fix my speedo..there is something type of jet chip that fixes it..but no one knows..i have already asked before. *

 

damn man.... thats some rain on my parade........dont you only have to use a hypertech once..... i mean like each time you want to change sumttin then unplug it..... couldnt someone who has one.... let people rent it........

 

hypertech is smart.....you can only use it on one car....meaning....if i have one..and i switch my settings...it wont work on no one car other than mine....if i switch my settings back to stock...then i can re-sell it....i had a change to buy one..but for 450 dllrs...i didnt think so..since they dont make them..people try to get too much out of them..but sorry....if you get a chip that can recalibrate our speedos...pass on the info to me please.

 

im sure you'll have better luck that me........ but yea im not worried bout the spedo its the shift points......

 

true..but i got a shift kit..so im not to much worried bout that..i need to fix my speedo..i raced a firebird on the weekend..and my car stopped...at around 120..i wasnt looking..but my brother told me..but that is only like 110..cus my speedo is off by like 10 mph so the bird beat me..well i beat him but we were still going..i was going till he stopped..but he didnt..so i didnt...in the 1/4...i know i beat him.

 

JCWhitney.com has a jet chip for TA's for $129 (81-85), $ 199 (86-93). Plus they have a Hypertech programmer 3 for $354 (96-2000) Firebirds and Camaro's. If ya have the catalog it's page 92. If ya dont, go to the site and order a free copy. Hope it helps

 

that would help bro..but you are in the v6 forum..and only hypertech programmer out there is for a 2002 v6 i think.

 

yea we have the 3.4's

 

i got a hpp3 for my 2000. it says its for 2000-2002 V6s
but it wont program for 3.73s! it only allows you to change the programming for 3.08, 3.23, 3.42s. now why would i go from 3.42s to 3.08s? luckily i could change tire height to 24 inches and that did the trick.
sorry, i have never run across one for the 3.4.

 

SLP makes a speedometer recalibrater don't they? I'm guessing it would work with a V6 too. It's really not that big of a difference, stock you have 3.23's. Switching to 3.42's your speedo will only be off about 5-7 mph.

 

thanks for the info...... what about the shift points........

 

I don't think the shift points will be off enough to make a difference. My friend has a 98 WS6 that originally had 2.73's and then the previous owner put 3.73's in. His speedometer is off by a lot but the shift points don't seem to be wrong.

 

aren't shift points figured from the RPM's anyway? just because you have different gears shouldn't change the fact that the tranny will shift to next gear at 5400rpm or whatever it may be. your speed at this rpm will be different (less), but you'll get there faster with your new gears than the stock ones, so you'll go faster. so why are you worried about shift points unless you did something to your engine as well?

 

thanks for the info........ some v8 guys from one of my boards just said they will be off......i was just wondering if this would be a bad thing.......
