What's the progress on this program? Care to give us an update?

That's a good question. I think Dave is ready to release it.

Got the VE in? How's it run?

No, haven't got it in yet, waiting for the RTv2 files :p. And he told me that I had to put the file you sent me through Blinker, to create the proper file for the ECU.

Gotcha. Btw your board (with any firmware) will run normal bins just like any other daughterboard/emulator/whatever, so you can use that if you want to get the swap rolling. That will run and drive just fine, just no cam switching. Plenty good enough to test the swap though.

Hmm, thanks for the update!

Anything that should be changed to the setup then?

Btw, will compression matter? And if so, what should be changed if I turn out to have a higher compression than stock (Since having SR20DE crank and rods, with SR16VE pistons)?

Yes, compression will matter. I would guess you will need to retard the timing, how much over the stock VE does that raise you?

What's blinker?

Blinker lets you import and export bins in and out of TunerCode format. Basically you can hand it a stock-based firmware based bin and convert that to a TunerCode bin, or you can take a TunerCode bin you've tuned and convert that to a stock based bin. It supports importing/exporting both to TunerCode optimized for the Realtime v2 and TunerCode optimized for traditional setups (Realtime v1, basic board, etc).

Part of the design process was to specifically support importing a JWT bin to TunerCode. This makes it dead easy for someone that owns a JWT ECU to migrate to something TunerCode based.

This is all currently for the B13 only of course. Blinker is 100% from Dave, I'm just a user. :)

SR20VE (Stock): Should be 10.3:1-ish
SR16VE (Stock): Should be 11:1-ish

And according to various sources, the CR of a 16VE piston in a 20VE is either 12.1:1 or 13.5:1.

I'll ask the guy I bought the motor from what pistons he actually used.

I'm still working on the documentation so folks can figure out how to use TunerCode and BLinker when they get them.

As Calum says, BLinker (or Bin Linker) lets you export your tune data from a stock or TunerCode bin, and import that tune into your TunerCode bin. It does not support importing tunes to stock bins. What this means is that if you have a bin already tuned and want to upgrade to TunerCode, you can export the tune data from your tuned bin and import it into the TunerCode bin. It also allows you to share tunes with others without transferring the entire TunerCode bin (which would violate your license agreement).

Edit: BLinker is also handy if you have more than one tune. Once you have a tune the way you like it, you can export it so you can easily go back to it in the future.

Cheers,
Dave

So, Calum, would you have a solution to my problem? Could the fuel-mapping be retuned, for example, so I can use RON98 with the high compression of 13,5:1? Or would I have to swap out the pistons? The problem is that we only have RON98 around here. Higher numbers are rare in The Netherlands...

No, sorry. I've never worked with anything other than a stock compression VE, and I've never worked with anything other than US gas. I would guess you will need to retard the timing. I hear that you can adjust it via that ECU you've got. :P

I would watch the knock count in TP5.

Ok, thanks. I'll go see if I can find another solution.

I wouldn't trust any pre done maps for that setup with your different gas. This is really a case of where you need to tune because your application is unique.

Hmm, then I should really start reading into changing fuelmaps. Haven't got a clue yet XD.

BTW, RON 98 (Euro standards) is about 93 AKI (American standards).

I think the fueling you can leave alone (although ideally you would want to tune that on a dyno too, but not a big deal). The timing map is what you need to adjust (and just at WOT, so the last couple of columns).

I would take the last three columns and pull 6 degrees of timing across the board. Start to feed it back in until you see signs of knock, then pull back out.

93 is what I work with, that's cool.

The TunerCode documentation explains how the fuel and timing maps work.

Calum's suggestion that you get the engine installed and running using the stock bin is an excellent one to heed. You will want to minimize the variables to test the installation.

Kay, thanks for the suggestions. But I still think I need to lower the CR somehow, to be able to run on pump-gas (RON98, 93 AKI).

However, if you say I can tune the ECU to run on RON98 with 13.5:1 CR, then I'll go see if I can do that. If not, I need to change pistons/switch to a thicker head gasket.

Bump :P
