efi chip burn tuning v6
i want to learn to do this, ive read loads but theres a bit of a grey area, from what i understand i need to remove the chip and put it into a chip reader which plugs into my computer,
now can i not with the right cable and software just plug my laptop straight into the cars onboard conection, and play from there ?
thanks

Re: efi chip burn tuning v6
The stickies at the top of the diy-prom section are the best place to start. Alot to read and you'll be pretty clueless until you actually get your hands on some tuning equipment, but everything comes together eventually. Just keep reading and experimenting.

Re: efi chip burn tuning v6
You'll need a laptop, aldl cable, chip burner (willems makes good cheapies), an eeprom chip and a copy of tunerpro. You'll also need the appropriate definition file for your ecm ($3A for the 1227302) which you can download from moates.net. You're kinda limited with the '302 ecm because there's not alot added to the definition files available and I'm not aware of any publicly available hack of $3A either. If you want more control you'll need to swap in another ecm like a '730 or '165.
-Oh, and the '302 ecm doesn't have a memcal like the p4 ecm's, you just pull the eprom from it's holder.

Re: efi chip burn tuning v6
It'll be easiest to learn on the '302 then switch to a better ecm once you have the experience & recources (like a wb02) to do some real tuning. Learning to tune is totally worth it, gm left alot of power and especially fuel economy on the table with the stock tune. I've found that my motor wants alot more fuel at wot than gm gave it and that these little motors are alot more responsive than the stock accel enrich tables allowed for. I've been focusing on economy for a while now and made some good gains, but I think there's still more left in it with better fueling strategies.

Re: efi chip burn tuning v6
sounds awsome, i cant use mine daily at the moment just too damn'd expensive but if i can get it tuned for economy and then have a seperate file for performance that would be sweet. or just finding the right fueling for my daily cruise rpm would be good. cant wait now ! thanks

Re: efi chip burn tuning v6
The stock chip is fine with stock injectors. It even works great if have a high flow trueleo intake manifold. http://trueleo.com/f-bd_radif.jpg BTW: that intake has a custom TBI.
Also unless you go to forced induction theres no need to for bigger injectors especially so with a stock or bored-out stock intake, they will just make the fuel mix even richer above 4k.

Re: efi chip burn tuning v6
That's the first time I've ever read that about the DIY PROM forum that is here in TGO. Read the FAQs, there will be quite a bit of info you won't need, just to get started, but just about all of it is good to know.
im sure it will be more helpfull once i get started,
'302 being limited is prob a good thing for a newbie eh ? is it really guna be worth the effort ? and do you think ill get much out of it ? im guna do it anyways just to learn.

Re: efi chip burn tuning v6
can I use chip burning with my ecm to turn off my emissions SES lights? I bypassed most of the emissions and want to tune for more power and drivability.

Tuning anything can be helpful, even just from a learning perspective, sometimes the limitations of certain code can play against you though, so keep that in mind when you get to something you just can't seem to tune around. Also fix any and all known mechanical issues BEFORE starting to tune. Tuning around mechanical issues will just be more aggrivating than it's worth and will usually end up with less than spectacular results. If there seems to be something that you just can't get tuned properly, and seems like a mechanical issue, it more than likely is.

Re: efi chip burn tuning v6
If you have a very modified NA engine, hi-flo intake with bigger TB, eq-lenght headers, higher comp pistons, head work, wild cam, bored out block, etc etc, you may want to burn a new chip, but dont bother if dont you have a wideband to monitor what each burn did. Yeah you can use a dyno, but that will get $$$, go to the dyno when its all done.
Check out the link below I think you find it quite interesting. It compares a carb vers hi-flo FI intake on two dif engines.
BTW: the headers on both were Sprint and not equal lenght at all and they have a small dia Y pipe -needed on Fieros- the collectors are not best design either, thus you should see more gains with the better f-body designed headers available.
