thats just what the FAQ says to do..

ok, i get it ... now when im scaling down the actual map in rows and colums, say i want to lean it out a bit around 6500rmps.... now at this point i will obviously be at full boost (8psi)

so would i pull fuel only from the colum for 8psi? or would i pull if all the way across the boost portion of 6500rmps

these are just a few things that i dont really understand being that im just starting to understand tuning a bit, well i understand tunning, just never gone and done it for myself..

also whats up with this closed loop, open loop thing i keep hearing about datalogging

projekteg

no, that would be advacning timing und-er boost. for about 10 -12 psi, you want to be around 18-20° in the high rpms.

projekteg

closed loop is when the ecu is making a/f corrections (at part throttle) based on the o2 sensor readings, when you go past part throttle, the ecu is forced in to open loop where it starts going off of the programmed rom. have you ever watched an a/f gauge? see how it bounces back and forth when you're cruising? b/c the ecu is constantly making corrections. notice when you floor it, it stays steady? that's b/c the ecu is no longer making the corrections to it, it's running off a set map. it's just easier to tune in open loop b/c the ecu isn't making corrections making your numbers jump all around.

even pulling a pull degree per psi on the uber chart the timing doesnt get that low, and of course the morse boost your running the more timing u want to pull...

im gonna run 8 pounds, and i hear that pulling a full degree was a littel comservative... i was gonna try .75 but it looks like at 6500 rmps that the timing would be 28.64 ... u think that is to agressive

also, whats up with these charts, the higher i get in the rmps it seems the biger the gap in the rmp reance ... the colum goes:
5189
5626
6500
7940

is it me or are those really big gaps for tunning

projekteg

stock timing is about 26° at redline, you telling me you're going to add to that? i think you're doing something wrong

92hatchattack

ok, your right... am i then correct in saying that when the map sensor senses boost it advances the timing

what static timing is everyone runing their dizzy's at

and at what point would u end up with to little timing i hear if u pull it too much it will really spick up you egt's...

and let me just take the time now to say thanks for all this help.... i really do apreciate it ...

oh, and those intervals dont seem too big for you does the program autmaticaly set the fuel and whatnot between the two rmp levels depending on what they are set at??

projekteg

set the dizzy to stock timing. gererally when doing timiing maps, i don't do a linear retard like set up in the program. i set the ign. retard to '0', then go in and manually set the maps. 0-3 psi gets no retard, 3-6 psi gets .25° per psi, 6-9 psi get's .50° per psi, and so on. this is called a step retard and makes for a much smoother transition in to boost and doesn't rob power where it's not neccessary. have you been to the uberdata forum? a lot more info. there http://www.ecimulti.org/uberdata/forum/

very cool, i dont think ill set my own maps myself just yet, ill setup everything with the set up in euberdata, and maybe after my car is up and running good, during the tunning process i will start to play with thouse things a little bit more when i am really feeling more comforatable in the program ..

yes, ive been to the uberdata forum, i just havent registered, so i guess i gotta get on that lol
