OpenFlash Tuning Tutorial: Crawford Billet Power Block Mapping changes

[Stumpygt86]

Was looking at getting the OFT. Are there Australian base tunes that have been worked out for our 98 octane fuel, (including the Power blocks)?

Email Shiv for a BPB modified version of Steve99's 98RON tune - I've been running it for about 6 weeks now without any issues but with all the benefits of the shifted torque/power curve the BPB provide.

see thread in this sction have modded up some manual roms for 98 ron fuel based on latest V2.04 tunes, BPB mods are very simple to apply se OFT TIPS thread below.

see also knock fix thread below also has some older roms lots of aussie guys used

just read all the links below then you will be sorted

Question.
Im running BPB on E85.
Am I better off using BPB tune of pump gas or sticking with E85 EL Tune?


Thanks.

Have you done any custom tunes with this setup?

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

One question for you shiv@openflash I have followed your steps above in preparation of my bpb to arrive any day. So while I am changing timing compensation in cylinders A and B.....why is there no change to C and D? Sorry if this is a very noob question. Just trying to get an understanding of what it is and why I am changing it....Thanks!

[Triumphrider]

Based on what I am reading concerning knock it looks like I am better to tune for 91 and run 93 with the bpb installed...maybe someone can chime in if I'm totally misunderstanding this.

[Triumphrider]

So I had no trouble opening these in rom raider made the required changes to the tables but when I save it, It doesn't save the timing compensation changes for cylinder A and B. Knock correction advance max A saves fine.... Any ideas?

[Triumphrider]

Got it... Stupid mistake

Grrrr even with user level at the highest setting it won't save :mad:
