I don't think my ve table even goes up by 25% at 320kpa. But yes, start with a value that you know is rich and lean it out from there.

 

Okay boys. I got the new map sensor in with FIC 850cc injectors and a vacuum block. When I fire it up, it will start for a quick second and then dies. When I scanned it, the MAP stays on 22 kpa. Am I just not getting signal from the map or do I have the MAP linear and offset off?

MAP is part number 12223861. Linear is 308.20 Kpa and offset is 1.11 Kpa

 

Check voltage output with key on. Should be in the 1.5v range.

 

I'm getting 5v

 

Okay as i figured, the cheap *** map I bought on ebay was a dud. Last night I ordered the MSD 2313 map from summit and got it installed just now. Fired up and I'm getting good MAP readings . My dynamic airflow is the same as calculated airmass now with the 3 bar OS. The fuel trims were between +30% and +50%. So I will get tuning on the VE.

 

Here is a log. Why would my bank 2 STFT be so much higher than bank 1? The truck has open headers right now so I don't know if that has something to do with it. Might be getting weird readings since the O2 sensor is in the collector..? I don't know

Another question. I'm getting a MAP linear of 308.19519 and an offset of 1.10 for part number 12223861. Do I adjust the offset until I see the correct barometric pressure for my location when the engine is off and key is on? Or do you guys just roll with the calculated offset?

 

Could be a bad O2. I have seen that before. Even if it switches it doesn't mean its accurate. For the MAP, just go with those values. The MAP sensor is absolute pressure; it isn't relative to location or elevation. If the linear and offset values are correct for that sensor, it will be accurate.

 

Golden, thanks Jake. Turbo kit should ship at the end of this week. Then the real tuning begins.

 

Okay the truck is up and running. Fuel at idle seems spot on. Haven't driven it yet because I need to set up a spark table. Can anyone help me out with this? I'm guessing I need to start out around 12-14 degrees in the higher cyl airmass parts of the spark table. Can someone upload a sample table for me so I can see where I should start lowering the spark?

 

Okay made a bunch of changes and I need help from you boosted guys. In the log, you can see in frame 697 that I am getting some mean knock because BE is really delayed. The truck is in boost for a few frames before it kicks down into BE. Is there a reason that it is so delayed? It happens again at frame 1602. Maybe I just set my BE enable to 95kpa or something? Thanks guys
