OpenFlash Tuning Tutorial: Crawford Billet Power Block Mapping changes
Hi guys,
As promised, here is a tutorial on how to adjust any of our gasoline OTS map (91 or 93) to work well with the Crawford Power Block. Of course, additional dataloging/testing is always a good idea. But the changes outlined below are easy to implement and will work well once you add BPBs. Note: This tutorial is only intended for our gasoline OTS maps. I never had too much success with running the BPB on E85. Using Rom Raider, open up your current OTS map (Stage 1, Stage 2, Stage 2 UEL or Stage 2 EL) view the following tables: Knock Correction Max Advance A Timing Compensation Per Cylinder A Timing Compensation Per Cylinder A It will look like this: Step One: Set both Timing Compensation Per Cylinder tables to 0. Step Two: In the Knock Correction Max Advance A table, copy the entire 6000RPM row and past it in the next 5 rows (6400, 6800, 7000, 7200 and 7400). Once you are done, the tables should now look like this: Step 3: Close the windows. Save the file under another name (i.e., Stage 1 BPB A01C). Step 4: Close and re-open the file. Step 5: View the three tables you changed and confirm that they changes are there and exactly as shown above. [Steps 3-5 are just for the sake of safety] Step 6: Load up the revised BPB map into your OFT and flash to your car. As always, let the engine idle for a minute after first start-up before driving off. Go ahead and run the car. You will feel some good power gains above 6200rpm. Along with the good power gains that the BPB provided between 5200-6200rpm. Step 7: Take some datalogs of 3rd gear WOT runs (2000-7500rpm) and confirm that there is little to no knock correction. Especially above 6000rpm where you made the adjustments. That's it! Cheers, Shiv Last edited by Shiv@Openflash; 08-01-2014 at 06:34 PM. |

Shiv, what's the reason for adjusting the rear cylinder compensations for this and not for the other tunes? Which I guess asks the question as to why they are there in the 1st place?
I know that zeroing out the compensation is a good way to make power but at what cost?

i'm trying to update it in romraider, but i'm unable to open the tune.
it always say "Unable to read XML definition. Please make sure the definition file is correct. If it is in a ZIP archive, unzip the file and try again" wich I did. I put your new XML, selected it, and can't open the tune. (note that i was able to do it with previous tune) |

Baring those solutions maybe you could try and re-download the 2.01 zip and try it all again. Maybe something got messed up inadvertently. |

i'm using the 2.01 one (never had the 2.0 since there was no solution at that time for BPB) and i've removed the older XML.
i've unziped it twice, but didn't try to redownload it... i will try right away. i've also double check with the old XML and an old tune to be sure romraider was ok, and it's was working. |

I flashed, waited on idle for a few minutes and now I'm not at home but I've looked on the tablet for a few minutes on the highway and I've noticed my advance multiplier fell from 1 to .88 and then at each 5 min it raised to .91, .93 and. 96
Is it normal at the beginning ? Should I worry ? I will post logs once I'm home |

Log again but this time uncheck VVT Intake and VVT Exhaust and select Knock Correction and FLKC and do another log for conformation. |
