Not sure if I've helped you before or not. I know that's the SD map I've created a good while back though. Tried giving it some throttle to keep it going until it warms up a bit at least? Might need a biss adjustment but can't tell because it's not running long enough. Give it some gas to help it out and then go from there. Don't see anything jumping out at me that looks wrong in the log though.

What's the best way to adjust the BISS to normal operation? It seems like it idles good until it warms up and then dies if I give it any throttle or put it into gear and as soon as I hit the throttle to take off it dies and doesn't want to stay running after that. Any suggestions?

 

[v8s_are_slow]

A log would be great. But have you tried having someone adjust it while you sit in the car with it in gear?

 

[AWD-Tony]

Yes log would be nice. What's your WB doing when you give it gas?

 

[donniekak]

What 1600's did you install?

Does your S90 have a ISC?
Assuming your 1600cc injectors are High Impedance, did you bypass the injector resistor, and what fuel are you running?

 

[Myk984g63]

1600's are low imp. I have not tried to adjust while giving it gas. I will try that when I get home as well as post a log and pay attention to the wb. The injectors are Bosch. Running 91 oct pump.

 

[v8s_are_slow]

I didn't say while giving it has. Said while in gear. Huge difference. And get better injectors. Those are like the worst ever.

 

[Myk984g63]

Damn. I swear I have the worst luck on buying parts . It's the 3rd set cause the 650's and 850's I bought weren't working right.

 

[v8s_are_slow]

Get high impedance and be done. Sell those.

Get high impedance and be done. Sell those.

Do I need anything special to run high impedance?

 

[v8s_are_slow]

Just delete the resistor box on the firewall and install the delete plug. Can make one using the resistor box you just deleted if the injectors don't come with one so don't throw it away. Then the rest is just setting it up on ecmlink. My 2150cc injectors run just like stock. Flow tons more fuel.

 

[v8s_are_slow]

Only downside to them is price. But saves you money after going through 10 sets of injectors. Last ones you'll need to buy depending on how large you go.

 

[Myk984g63]

Okay. I'll see what I kind of cash I can come up with. Does anyone on here have a decent set for sale perhaps?

 

[Myk984g63]

heres the log from this morning

 

[Myk984g63]

Its idling pretty good, just curious if you guys see anything in the log thats a cause for concern?

 

[AWD-Tony]

Needs TPS adjusted to .63, ISC to 30, airflowperrev to .25

 

[Myk984g63]

ok I'll start there..are those all easy adjustments?

 

[AWD-Tony]

Yup.
For TPS, start a log then push the pedal all the way down and release. Then right click on the log and select TPS adjust.

ISC position - Get it to operating temp and with no load and fan off, adjust the BISS to get the isc to 30.

Airflowperrev - increase the cell in SD idle area.
