Ok i installed my dsm blue top 450cc injectors yesterday w/out any problem, went into 1.7, stockgsr, import p06, uncheck knock and vtec stuff, enter 450 into new injector and hit apply, burn the chip, runninn wayyy rich, go back, see theres that fuel modifires tab, didnt check enable, so i did that, still rich, so i went into the map and started takin away fuel, but it seemed that sometimes the more i took away the more it seemd to bog?? i dunno im just lookin for a little guidence on just basic manuvering on uberdata, just how much fuel does -1% or -10% take away? I got to the point where i had done the new 450 in the injector box, and had taken away about 7% from the whole map and when i drove around my a/f gauge was pretty much pegged into the rich the whole time, just how much is too much to take away?

UberTeg

you take away enuf to get your a/f down to a reasonable range. Might be a better idea to run someone's turbo basemap as its kinda useless to reinvent the wheel, a nd tune from there.

Scean

yea ill be installing in about a week so ill just get it decent and run a lil rich for a while, no biggie, i wont be driving much in the next week anyway so no harm should be done

I didn't notice you say you had a wideband on there.. without one it's like playing blindfolded darts.

Scean

ur right i dont, and i know i need one bad, but funds wont allow it just yet, im just trying to get the car to run decent stock for right now, them im gonna boost low w/ a conervative basemap until i can get my hands on a wideband

Shoot me an Email address and I'll send you the map I run in my hatch with 450's.

Taking away 1% seems to affect the air:fuel mixture more than in boost. I've had it change several tenths of a point just by subtracting a percentage from the idle cells.

What are the fuel values in your idle cells?

Scean

i guess my idle cells would be my around 1000 rpm at about 20 vac?
if so the 1000rpm and 19.82 in/Hg is set at 54.75

And it's only a 1.5L?

Scean

haha yea

I'll just leave you with this:


His car is a D16Y8 with a Crower Turbo cam and DSM450 injectors, and it likes to idle right around 19" to 20" Hg and 800rpm.

It liked to idle around low 14:1 AFR's. I think I still need to add more fuel in the second column b/c it likes to lean misfire on cold starts still....I just need to confirm it with the wideband again.

Scean

wow, mine is so different, i mean right now i am trying to run STOCK so itll be difffernt, but i just created a basemap for boost real quick, and when your 500 row goes up slowly, 7.0 12.0 25.75, Mine skyrockets 2.13, 47.2, 73.07, why the heck is that?

VTC_CiViC

Depepnds on the size of the squirter.

Mad Cow

Non-wideband users are always such unbelievers. I was in the same position a year ago, and I even ran VTC_CiViC's map... Took me about 3-4 months before I tore it down and found 4 broken ringlands.

Get a wideband before you tune, no matter how safe you plan to run.

That really sucks. I made a basemap, and just put the my wideband on it and it was perfect. Just tuned by reading plugs. It was 11.2-12.0 at full throttle and 12.7- 12.5 in dip in boost. It was also 14.6-15.0 cruising. I couldn't believe it. BUt I think it is still best to make a basemap for youself.
That is just me.

Scean

i dunno whats goin on, but i got a week or so to figure it out
i also have a couple ppl who have sent me their basemaps w/ similar setups so i guess i can use theres and tweak them

so you really dont think ill be safe no matter how conservative the basemap is?? geez, well i cant afford a wideband, but i guess ill have to find someone in the atlanta area who will let me use thiers and maybe help me tune for some kinda fee

I started exactly how you started. It wanted to idle at around 10:1 AFR's on the startup map with those same mid-50's values. What you see for that LO cam map is an ok street tune. You'll need to lower the fuel values, of course, since you have a smaller engine.

In my experience working with Uberdata on that engine:
What's funny is that if you import a P28 on top of the StockGSR map, the fuel values get even richer. That was kind of unintuitive for me, so I started working directly off of the StockGSR bin without importing the P28 map on top of it.

The only issue I've found is that it'll lean out when you start the engine (warm or cold) before the air:fuel mixture will richen up to the target AFR over the course of ten or so seconds. Until then it'll be lean enough to lean misfire for a few seconds. The rpm and vacuum levels at idle are constants. I don't know what the issue is, but it's not a major problem since it only exists at idle conditions for a short period of time.

Scean

thanks for all of your info ,
also, you may have misunderstood, im running a d15b7, not a z6, so i import the p06 and dont mess w/ the p28

I know this may be a stupid question... but, you did install resistors right?

DSM injectors are just hard to idle, period. But my idle is actually in the 11s too. So it is actually really rich. And I even leaned it out.

I have the same issue with my B16. From what I understand it's due to the IACV differences between the 1.8L (P72/P75) and all the other engines we're screwing around with. Or at least that's all I've heard to date.

I'll put up with 10 seconds of weird idle for Uberdata

I guess I'm lucky? I've got a nice 14.7-15.2:1 idle & part throttle cruise

I have great part throttle and cruise. I just didn't tune my idle yet. Don't know why. Guess just lazy. I just turn the SAFC down a few clicks... haha

I have a turbo B7, I ran my turbo basemap NA for like 400 miles and it got like 30 mpg and never bogged, let me know if you want it.
