u7137 part throttle tuning

[TYPHOON4X4]

well ive modified the stock tune and im wondering ! the part throttle selection! i have no idea what there for and what do they do? im more concerned about fuel economy for now .ill upload the performance tunes when required like towing etc.

[brandy16]

What vech and predator. Is there a part throttle selection?

[Mike_Levy]

You can't tune part throttle. Only CMR dealers can. Its also not a good idea to keep tuning and untuning the PCM. You're confusing it and it'll never run up to its potential if you don't let it learn.

[brandy16]

I tune and untune all the time The car dose not learn a tune. It learns how the car is driven and makes adjustments. Where did you guys get the idea that the car learns the tune. The tune is written and the car performs according to the way the pcm is written by the tune. After the tune is installed if you don't drive the car aggressively the car will learn the way you are driving and make adjustments maybe. The car dose not start out knowing nothing and then learns the tune The tune is written there is nothing to learn.

you just said it learns how the car is driven and makes adjustments, every time a tune is installed it resets the computer making the computer have to learn the tune and how you are driving. that's where that idea comes from. if i switch tunes it runs like crap because it has to relearn everything while adapting to a new tune. in my opinion if you don't let the tune settle in it won't live up to its full potential.

Please use what God gave you. The tune tells the car what to do it dose not have to learn it. The tune has been written to the pcm. As soon as you write the tune its there all of it. When you write a performance tune the performance is there as soon as it is written. The learning part comes after the tune is written and the car has been driven. If the car is not driven aggressively then the car detunes it self to fit the way the car has been driven. You know not driven at WOT ect. Driven slow ect

[Mike_Levy]

It resets every time you install a tune and uninstall a tune. If you keep doing it, it never actually learns the driving and its running on just the tune with no adjustments.

Sometimes I wonder where you get the stuff you post. Its like you're living in your own little world. It has no bearing on how things actually work.

what i mean by learning the tune is this, every time you install a tune it resets the pcm and clears the adaptives and until they are learned again it feels like its fighting the tune. once they are mostly learned again that's what i consider to be settled in.

[bighemitex]

i'm fairly certain the pcm reset and loss of adaptives is behind the problem when people go to the track and switch tunes and run almost the same time or when they are on the dyno switching tunes and making the same power as stock. it needs time to set all the adaptives so the "one size fits all" canned tune can become better suited to your individual vehicle. with my other tuners i used it was recommended to let the tune settle as well so the adaptives could have a chance to set again. it's very rare i switch tunes, maybe 10 times a year depending on how i feel.

[brandy16]

THE ONLY THING THE PCM RESETS IS THE TCM ADAPTIVES WHICH ARE TRANSMISSION SETTINGS. IT DOSE NOTHING FOR TIMING FUEL SPARK ECT. SO WHAT YOU ARE SAYING IS NOT POSSIBLE IF YOU DON'T BELIEVE IT AKSE DIABLO SPORT. YOU DON'T LOOSE POWER ON THE DYNO SIMPLY BY SWITCHING TUNES YOU MAY LOSE POWER BECAUSE OF THE DIFFERENT SETTINGS IN THE OTHER TUNE (IE TIMING FUEL ECT) DIABLO DOSE NOT MAKE A TUNE AND THEN HAVE TO DRIVE THE CAR TO GET IT TO SETTLE IN. THE ADPTIVES CONTROL THE TRANSMISSION, HOW HARD OR SOFT IT SHIFTS (TOURQUE) THATS WHY THEY CALL IT FIRMING UP THE SHIFTS. LAST BUT NOT LEAST. WHEN YOU RESET THE TCM ADPTIVES IT FIRMS UP THE SHIFTS AND MAKES THE TRANSMISSION MORE RESPONSIVE. NOT LESS RESPONSIVE.Ii THINK THAT NO MATTER WHAT YOU ARE TOLD OR WHO TELLS IT TO YOU YOU WILL NOT BELIVE IT. PLEASE GET WITH MIKEL FROM DIABLO AND ASK THE SAME QUESTIONS

[Mike_Levy]

We'll see what Mike says on Monday, but I'm fairly ceratin engine adaptives are reset when the tune is installed or removed.

yup

[brandy16]

There are no engine adaptives. They are transmission adaptives and they are not reset with the tune. You must reset them. You can do it when you install the tune or any time after. You have to modify tune in-order to do it. When you install a tune you select the tune you want and then select modify tune. That will take you in to all the things that can be changed like turning the MDS off resetting the tcm adaptives, changing the timing, firming up the shifts, ect When you are done with the changes you hit esc until the predator ask you if you want to install the tune.

I have the 91 oct tune installed, but don't have any trans adjustments options under modify tune parameters or in quick adjusts. I looked under modify stock tune and I did have some trans adjustment options, but have not tried anything yet. Not sure how the modify stock tune works? Does it adjust the settings of the 91 oct tune or do I have to install the orginal back up for the modify stock tune options to work?

[brandy16]

It modifys the stock tune. You should have the trans mods under modify tune. When you select performance tune then you select which tune you want. and it will have modify tune at the bottom. select modify tune and you will need to page through until you find the trans options After your done you can hit esc until it ask you if you want to install the tune. These instructions will give you a better explanation You will also find information on why and how to reset the TCM adaptives http://www.case-enterprises.com/xeryder ... edator.htm
