Ideas for Tunage

[aaron ford]

Thanks for the replies, guys. I suspected that there was some reason for not having a progressive shifting tune.

I hate my stock TDE1 shift pattern. I am hoping the 65P tune or the 65tow will allieve my issues. It does odd things like upshift under a throttle increase at 2200. On a full power pull, when the TC locks in second, the third shift is only moments away. The two events drop the engine below 1500 and out of any available power. For some reason, it shifts better cold.

My throttle acts like an on-off switch which may have to do with the 15K resistor in the ICP harness. This resister willl be long gone before installing the Phoenix. That is why it was never mentioned.

Thanks,

Aaron


PS, Dry laundry detergent is cheaper than gojo. Just wet hands, pat both sides in the detergent, wash as usual. Hope you don't have any cuts on your hands cause it'll send ya to the moon. The only van experience I had was pulling a 351w and the van was going to the scrapyard. That dash was trashed!

Did the laundry soap stuff for years as a kid working on mowers and dirt bikes. The nitrates in that stuff will seriously piss off any cuts for sure! In a pinch I still use it, but any more I have a gallon of GoJo in the mud room for quick cleanups on those greasy jobs.

As for the 15K, that probably has more to do with the crappy shifts than you realize. What people fail to remember is that all the shifts are based on throttle position and anything that changes the relationship between throttle position and engine output is going to screw with shifting, even if it is indirectly.

Consider... Let's say you were stock and it takes 40% throttle to accelerate 2 mph per second. Now you change the power output (10K, chip, whatever) and now it only takes 25% throttle to accelerate 2 mph per second. If you don't take into consideration the shifting, then you end up with shifts that could occur anywhere from 2 to 8 mph earlier (depending on the shift), which would result in lugging and possibly even shift hunting.

When we do chips or programmers, we try very hard to maintain good low-throttle characteristics and a power transfer curve that is similar to stock. Once you get over 40% is when things really start cooking but by then the shifts aren't nearly as critical.
