Speed Calibrator on The Mark

lol Yes sir, just when you think your done, more mods. :) I first want to get some seat time this spring, and practice rolling into the throttle rather than my usual technique of matting the gas and not lifting. Aric had good success rolling into the throttle while working on the car, but I suspect that is not going to help the 60' time any.
 
Mike, even if you turn in a 3 second 60'time nobody is going to care when you get the 11 second time slip. Keep up your great work.

Thanks for the info, Charlie.





Thanks JP. Glad to hear it is working for you.





Thanks for the info, Doug. I will pass the info on to Aric.









Thanks, Mike. After reading all the replies, it seems that the VSS gear should be returned to stock, and then see what we got, and go from there.

I agree with you, that our cars are very close in mods, and it is good to hear you do not have this issue. If I recall correctly, you have a stock 98 trans in your car, and probably a jmod? And the only thing done to your trans tune is your tuner just raised your shift points and tc lock up? Anything else done to the trans tune that you know of? Is your ABS still working? Mine has had issues for a year or two, and I wonder if that might play into it somehow.

If all else fails, maybe I could have Aric call your tuner to see what is different between your shift tune and mine? lol I am willing to do just about anything to get this fixed. :)

Am I correct in inferring from this that a 4:10 rear end in a Gen 2 does not require a Speedcal or a tune? My car is stock although I want to do some mods later. I have the rear end and a '93 driveshaft. Will the driveshaft work in my '98?

You do not need a Speedcal or a speedo gear. You DO need a tune.

The '93 shaft will fit, but may not be good enough to eliminate the vibrations caused by the higher rotational speeds due to the 4.10's.

Thanks guys. What kind of things would the tune adjust? Shift points? Sorry for being a noob but I just got my Gen 2.

The tune needs to adjust the N/V, which is a calculation that the transmission uses to calculate appropriate shift points for the new gearing.

Past that, there are a number of things that you may want to adjust such as shift firmness, A/F ratio, timing, etc.

You should contact Lonnie @ BOC and let him advise and help you.
