I have been helping out several buddies over the years with F-bod's and now a lot of them are going the way of C5's. OL SD is very simple on DBC set ups, but it seems to be a bit more tricky when DBW is introduced. All of these cars (3 in total) are mostly raced and MAF and O2's aren't needed, so OL SD would be a great choice.
For DBC, this is my process:
Download and change OS to 1 bar OL SD
Unplug MAF
Uncheck MAF SES and move the pull down to #2 "No Mil Light" for all MAF DTC's
Zero out MAF table
Disable STFT's and LTFT's with the drop down
Move LTFT Enable temp to 283*
Move DFCO to 283*
Uncheck all O2's SES for bank 1 and 2
Set MIL to #3 "No Error reported" for all O2's
I multiply VE by 1.1 as a starting point and data log Target AFR against actual WB readings
PE gets changed to:
Enable 2400 rpm
Change enrichment ramp in to fastest setting of 4
Set PE Multiplier 1.148
Disable CAT Over Temp
If the car has injectors obviously I adjust for that.
I have found this to be a great starting point for DBC. From here it is very quick and easy to get the VE table dialed both part throttle and WOT.
When doing this process with a DBW C5, I often run in to "Reduced engine power mode" which I think stems from P1514 and the like.
What is the best way around this?
Disable P1514 and it's counter parts
or
Raise the P1514 table some?
What other potential sticking points are there with a DBW car that might hinder a quick easy OL SD tuning platform?
I'd like to get all 3 of these cars to OL SD next week. Any insight would be very helpful! Thanks in advance!
