The KAM is stored on the ECU; this is why its very important to reset your ECU when you start using the J3, as it is likely you will change strategy and therefore the KAMs are redundant.
Interested in even receiving your partial tune. Make sure you give some info about the car & mods too. Maybe I will create a user section on the site to keep this info. I havent tried videoing 0-100 runs as they can vary due to too many other things (weight, temperature, road surface, ...). I do log each change I make to the bin (as I suggest in the guides) and log with my Innovate gear to a file representing the tune im using. The current chips only work with 64K bins; thats how you can have 8 switch positions. Jason

yeah i noticed that, whenever i made changes it was best to disconnect the battery to reset things, noticed this when fixing the idle as th changes wouldnt take until a ecu reset.
Neways pitty the 8 banks 8 tunes, i just use 1 lol loaded some on the other banks but once i make a modification it applies to the others too. i have a current bin i have modified. this one pulls hard for me all the way thru the RPM on both fuel esp petrol, Fuel economy has even been great. cant attach it to this post, so if i can send it to you via email to put up id be happy to give it to you to try. tune is for 97 el fairmont non hybrid engine, ph4480 extractors, wade 977b, vernier gear, brand new sprint gas setup, using pod filter, .8gap on plugs. |

Just wondering cause with a reset my car is a dog to drive constantly wants to stall, then after about a week of driving it gradually comes good. so if i was to download the bin off it before it resets wouldnt that be an advantage? p.s i dont really know what im talking about
 p.p.s. it has only been bad like that since i put a earthing system called hot earth on the car

Keep alive memory, needs power to keep the info in the memory. What hes saying is the when you rip the ECU you only can get the ROM memory wich has the program and static maps not the learned maps from the KAM. would be nice tho
Hence when you take the power off/ disconnect the battery, the ecu eventualy looses the data gained in the KAM. |

Correct.
There are plenty of docs on the site which explain these terms in great detail!

anyways iv been busy developing a good gas tune, for GAS ONLY, just gunna post up some of my findings
for example a lambda of 1.00 = 14.7 petrol and 15.7 GAS air fuel ratios. that chart is like that up and down the a/f just add +1 for lpg and ur on the money. and peak efficiency A/F on lpg is around 17:1 to 18:1 so lean on gas guys = good. and hence the higher heat range, im thinking to push the system more efficently i might take my sparkies up a heat range and lean my fuel out an extra notch. anythoughts people? also if anyone has any ignition map screenshot etc for lpg please post em up and please include A/F. |

lean on LPG will cause a lot of extra heat.
i'd be careful how lean you go there.

yeah, id be careful on the LPG AFR, youll do a headgasket or increase backfire risk too. having said that i have tuned for a stoich cruise afr with LPG (with great mileage results).
i can post the LPG ECU timing maps - will use the ignition map thread for it (just remind me if i havent done it in a couple days, work is busy). i have found that LPG has responded very well with my increased timing map which I made for 98ron (also in that thread) -- probably moreso than petrol. off the mark its much more responsive, only problem is my s**t gas system runs out of puff by the time i hit 4500. sometimes itll wind right out which ive never worked out - EFI is much simpler than dodgy LPG complex convertor systems 
amazing how much fiddling with the timing can change the way a car feels, even when you arent giving it a bootful.

how do you go about finding out what the deffiniton actually is? trail and error i suppose?

That 'sometimes it'll wind right out' - will usually be cooler days, with a cooler engine (cool induction). Very noticable.
Once it all heats up, its not going to go as hard - LPG is very, very susceptible to that unless your running injection. Now if you have injection - its all different. Cheers |

Not really to do with cool days, just the convertor leaning out. I can see it on my WB.
Definition creation is not easy; look on the site for a guide as to how we went about it. Jason
