** TIPS ON DYNO TUNING & STREET TUNING **

[MRX]

sometimes i think i'm an idiot...about the hard startup thing...i make changes and it seems like it works for just a bit and then it doesn't work anymore. Not to mention that the engine is at 0 vac when starting up and i start messing with 24.7 in/hg lol. Anyways i don't know how to fix the hardstart-up. It just keeps kicking my ass. But somehow i got gdout's f22b to start right up lol. And yes i tried using the same settings as him and it still didn't work

now u love open loop huh antoine?????

[MRX]

open up the program then try plugging in the usb..if its USB

What happened to the chip burner?

i dunno it just wont stay on when i go into the eprom program...bleh

[MRX]

so ur "uniform" theory does it apply in ever gear..? u know how the a/f slightly changes depending on gear (how big of a load).. well.. im curious as to how much variance there is between them when u get a chance

there doesn't seem to be too big of a difference in vacuum. Its seems to mostly be under WOT conditions or close to WOT. Hopefully i'll get a chance to even put my laptop in my car before it has to come off this weekend.

isn't the tps, cold idle and main enrich setting a little high? uber tells me to have 53 in all 3. just wondering where u got those numbers. could explain my 9.9 idle tho

uber gives u a "suggested" value...doesn't mean they're good values. I got the tps value from playing with the throttle. Just noticing how low the a/f gets when u immediately stomp the pedal. Remember when i had u "blip" the throttle a couple of times b4 making ur runs? Thats what i was calculating...the tps. Cold enrich upon research may actually be cranking enrich. I'll play with that later on. And no one is certain what main enrich is but i think it has something to do with the start up also. If u can get the f22b map i made from gdout that'd be great. Ur a/f is in the 9's cause ur idle plot is too rich lol. What happened to the chip burner?

edit: closed loop is when the ecu reads from the 02 sensor, by disabling it u run strictly on the map values that u set out for it. The 02 sensors input makes the ecu try to change all the values to 14.7. I'm gonna get as close to 14.7 as i can in vac and then enable closed loop. I don't need the ecu messing with my values right now.

[iamanonymous]

what is closed loop? i currently have it enabled and my chip burner took a crap on me...

[iamanonymous]

As stated in the chipped ecu thread i'm currently using uber 1.7 with great success and i wanted to tell you how i started tuning it.

First i simply copied and pasted the current turbof22v16 map to a stock dx map in 1.7. Set the rev limits, turned closed loop disable on, put the tps at 60, cold idle at 60, and main enrich at 80 also. When i first started it up it was way too rich so played with the cold idle setting a little more and got alot of the richness to go away with an 80 setting.

When i first started it up it was way too rich so played with the cold idle setting a little more and got alot of the richness to go away with an 80 setting. Didn't have the wideband on cause i didn't know i was gonna be tuning but i got bit by the bug and couldn't stop. Threw the wideband on, hooked up the laptop and started playing with the idle first and foremost. After i got that in the low 15's i moved on to other points in the map cause i was gonna come back to the idle eventually anyways. If u have a boost gauge you'd notice that if ur in neutral and hold a rpm at whatever rpm your at 21 in/hg in vacuum. So what better way to start off than to tune that entire column since the vac doesn't change with the rpms.

After about an hour or so i'd gone from a/f's in the 11's-18's to mid 14's-low 15's all throughout the rpm range. I simply took a notebook and made a list of my rpms, what the a/f was at that rpm, and how much i adjusted it. Keeping track of how much u adjusted it can tell u how much to adjust it on the next log. Seems like adjusting 5% can make up to a 1 point a/f difference in vaccum. The reason i concentrated on just that one line is because the other lines from 24.7-3.60 in/hg basically share the same increases and decreases. It's like the lines have the same shape but just increase in overall fuel. So i simply made the spaces between the columns as uniform and even as i could and it turned out to be a very smooth ride. Went back and adjusted the idle some more and got rid of a slight dead spot at 2700rpm. Been driving on this map since sunday now and its been treating me quite well. I still need to get another 2-4 hours of tuning in for gas mileage purposes and then make sure that the fuel in the boost columns is still flat. I did a quick rip of 2nd gear and the a/f's were in the 11's for boost so its atleast safe in case i need the power. Keep your eyes peeled

i'm bored...somebody ask a question.

Tip of the day: Having a hard time starting the car? Try richening up the very first part of the map at 24.7 in/hg and the first two earliest rpm's.

haha. you should do a "tip of the day" everyday! and make it a sticky

hmm i will try it.

[iamanonymous]

well then obviously u need to set a specific a/f as a goal, then get it there by adding/subtracting fuel where needed....how hard is that? GOOOSH!

haha thats the easy part......timing is the bitch....dyno time costs too much dinero.

[MRX]

fyi i meant about wot conditions with wavey a/fs sucka..
