Where do you get 29c256 chips?

 

:sigh:

-PHiZ

 

this is amazing

 

Cornhusker, also pull timing in the 4500 row.

Rob: Noone is allowed to sell my software or the chips, read the disclaimer. Noone should just buy a chip anyways, an eprom burner is cheaper than an afc, and much more accurate.

Only if you know how to use it! The AFC is simple... VERY simple... works with all OBD versions... I don't have extra OBDI ECUs laying around to play with.

 

Hey blake, hows it going. Did you get my email?

I am pueblo, and you email is hidden so i dont kno w hat you may have sent me (peublo)

 

Oh, dear god, how could I have confused you with that intolerable nit wit

The white hand of saruman might be able to shed some light on it, or did you find this link on your own?

bump for the freeware

 

OKAY,so lets say that I go ahead and burn a chip to what I think is correct or get it as close as i ca (have WBo2) and say it falls lean a tad hear or rich a tad ther, can i use the AFC to adjust for any imperfections in the burn? I ahve an AFC but dont like the idea of the hack in that it still allows the ecu to add timing. this takes care of that as I see. any info would be great. this thread is AWESOME.

glad to see you around PUEBLO

Rob

 

Why don't you just do a pull, then reburn a new chip with corrected values?

 

i dont know, im asking the questions here!!!
hee hee
is that the way to do it? i mean the best way?


rob

 

best way is to just burn the changes, afc's are horribly inaccurate, plus calculatign exact fuel changes with different map cut % over different rpm's can be a real pita, especially when the afc isnt very accurate with rpm and map adjustments.

 

Well, I think so. I am no expert, my logic says:
1. Burn chip with rich base values and conservative timing.
2. Make pass, data log (with your wideband etc)
3. Edit chip you created in step one
4. Rinse, Repeat if desired
5. Do step 4 until you have succesfully tuned your fuel and timing, burn your final chip, make sure it works and enjoy driving your now perfectly tuned car without the need of the afc.

 

this sounds to good. so i DL the uberdata, how come only the low tables are filled out in the fuel and timing maps? this is the stock LS map. and i will refer back to the FAQ about how to add fuel and timing. thanks guys.

No vtec, load gsr they are there.

 

every thing else is the same between the two other than vtec? thanks for the quick response

edit: allso i still have to get a 3 bar map sensor to boost anything above 11 psi (or whatever factory map limits at) ?

What do you mean? The maps are different, or are you refering to something else?

 

i mean the values of the fuel map and the values of the ign map, are they they same between ls and gsr. Or are these maps evan starting points from where to begin your tune? or do you need to input everything for your self. Basically what I am asking is, can i use the gsr map since all the values are there on my ls, or are these maps evan designed to run your car, or are they factory maps. Im a little lost ifyou cant tell.

Rob

 

Those are the factory maps, chose one according to which engine you have.

Once its loaded follow the instructions in the faq to fill in the timing and fuel under boost, then scale for your injectors. The 'fuel high' tab is the fuel map your engine would use after the VTEC crossover. If your engine does not have VTEC you will not use this map.

Once you have done that you have a base map.

HTH

BTW, what is your engine setup, and do you have a vtec head?

edit: no, the maps are not the same between the two, thats not to say it won't run, its how it runs

 

So... does this freeware let you run over the stock map sensors 1bar ? Or is 11ish psi still the max ? Can we install a 3bar map, recalibrate the resolution for the map, then run 20psi instead of only 11psi ?

 

My setup is
ls block
10:1 je pistons on eagle rods ( I dont wana hear it)
stock head
450'S DSM
precision sc 32 turbo
want to run about 14 lbs
looking for high 200's to the wheels.

Okay so you explained why the map didnt have high values, thats because the LS doenst need them, there is no vtec x-over point. GOT IT
what i dont get, is how you know the values to begin with, how do i know what to put where for (x) sixed injectors.

Thanks
Rob

 

read the faq

From the FAQ:
1. Whip out a calculator, do 240/NewInjectorSize*100)+5
2. select the entire fuel map, change the math multiuplication multiplier at the bottom to the answer you got.
ie. 450cc injectors = 240/450 = 5.3333333333333
5.3333333333333 * 100 = 53.333333333333
53.333333333333 + 5 = 58.333333333333

3. Magic number is 58.333333333333

Please double check my calculations, its late lol

BTW, as of right now you can only boost to the stock map sensors limit &lt;11psi, unless someone would show me how to scale for a 3bar. I could have sworn I saw something about it.
----------------------------------------------------------------------------
13) Ok, I got all this ****, how do I tune?
----------------------------------------------------------------------------

First of all, you must scale the maps for your larger injectors since the stock maps
are for 240cc injectors. The ghetto way todo this, is to select the entire fuel map,
change the math multiuplication multiplier at the bottom to (240/NewInjectorSize*100)+5.
Then tune from there. This is ghetto because larger injectors dont flow as much at
Lower pulse widths because it takes longer for them to open/close cuz of their increased mass.
Thats why you add at least 5% back, maybe more if you have a huge injector.

 

add 58.3 to just the multiplication part, not where it says addition right under it right?
sorry for all the questions, andt thanks for not getting inpatient with me

allso it wont let me add a decimal, so just 58% ?
