Good Morning all.
Sorry that I'm just getting in touch now. Thanks to such a strange virus, the whole family can be at home at the moment......I could throw up!
Well, I hope it will continue next week.....

I installed a new trigger wheel 36-1 on the crankshaft. I also have two sensors that run in the original distributor (one cam and four cams). During the last test I could finally see a value under CAM 1 Sig Tooth in the diagnostic display, the one cam was connected. Flywheel mode is 26. But since the engine was cold and I forgot to charge the battery overnight, the engine didn't start. I would like to drive with the COP's, the car is used exclusively in rallying and I would like to try to get the maximum performance ;).
How or to whom can I upload and show my program? Maybe someone could take a look? And maybe someone has a basic card for me, so I can try it with it? All the maps that are stored do not correspond to my engine characteristics. Do you understand what i mean?
As soon as I'm allowed back into the workshop, I'll keep you posted on the new progress.

Best regards
Andreas

Post a reply using the 'Advanced Reply' option below the text area. This has a file header that says 'Attachments' - use that to attach the MAP file you are trying to use - either download / save the one in the ECU or whatever you've created on your PC. As long as its the DTA created MAP file someone / anyone can open it, vet it and hopefully advise later.

Hello katana.
Thank you for your support.

I tried it, see attachment/ picture. It did not work. I don't understand why, the file, see the second picture with a blue background, is correct. Or?

Best regards
Andreas

You may need to zip the config file, first, many forums will limit what file extensions you can upload. Saving as a zip file, then uploading generally works.

Hello Gadgetman.
Thank you, seems to be working.

FYI, I played around a lot. I'm only concerned with the basic settings so that the engine runs properly at idle. So please don't rip my head off if anything is completely wrong ;). If you have any questions, just get in touch. Just an example regarding the Main Ignition Map. For me it was just a matter of getting it started and idling. Last time I didn't get the car because the battery was too weak. Hence these strange values, got this information here from the forum, so before going.🙈

So please bear with me.

Best regards
Andreas

Good Morning all.

So, I can leave the house again...isn't it nice, this virus.....well, it doesn't matter.

I thought again about the trigger wheel and the TDC sensor. Does this have an effect on how the engine runs, see attached picture of a previous comment from me (degree disc and drawn position from the sensor)? Currently I entered 100 degrees but the motor runs at 260 degrees. How does the control unit calculate the position or what is the reference point? I can't shake the feeling it matters with this engine because it spins anti-clockwise. Shouldn't I then mathematically go into the red? Do you understand what i mean? I measured the position exactly as it was said in another chat here on the forum. That's where I get to 100 degrees BTDC, see attached picture. But because of the other direction of rotation, that's not the case. How is that calculated by the control unit or am I thinking wrongly?

If I can still do it today, I'll drive to the workshop afterwards.

Thanks and best regards
Andreas

Sorry about the attachment thing - odd requirement that a website dedicated to EFI can't natively upload map. files ! ! !

Anyway - don't want to sound harsh but have you read (and understood) the DTA manual? I had a look at the map. file you uploaded and you've ticked '2 stroke' mode, using tooth pattern 26 but not including info on cam wheel and I think the teeth before TDC is incorrect. I referred to the manual and each of these items is pretty well spelled out - page 100 on. Need to get the basic settings right first, then do a DTA oscilloscope trace check - this will give numbers that DTA 'thinks' are correct.

Hi, everyone.

So, a new synopsis.

@Katana, unfortunately it's the wrong file, sorry. Criticism is always good, at least I don't get it wrong ;) and yes, I've read the manual, not just once. I also have a translation here but sometimes it's hard to understand. But I try my best.😉

So, in any case, I'm starting again today from scratch. Compression required, ok. Timing checked, ok. All cables checked, ok. Cable assignment COIL Zyl1>10; Cyl2>26;Cyl3>18;Cyl4>1 correct? Cable assignment injector Cyl1>9;Cyl2>25;Cyl3>17;Cyl4>34 Correct? Crank Sensor > 12 and Cam Sensor > 22 correct? I think that's all correct.
Then used the oscilloscope with flywheel mode 26 and noticed that the "fire point" moved. I then tried Fjywheel Mode 24 because I could use two CAM sensors and tried the one with 4 cams here. "Firepoint" wandered again. Put everything back and worked with Flywheel Mode 26 again. Suddenly I was able to sensibly shoot down with the stroboscope. The engine did not start at sensor position or at TDC position. There were brief moments that he wanted but couldn't. I then tried to adjust the fuel via Start Fueling Map, no success. I set the main ignition map to zero degrees to check it with the stroboscope and it should also start when I change Firing Tooth on Startup.
Did I miss something or do something wrong? If someone had a good base map for a B16A, I might have been helped.

If you need any further information, just let us know.

Thanks and best regards
Andreas

Cranking with no plugs and one plug shows a good cam trace. 36-1 with single cam pulse, so flywheel mode 0. Sequential on or off, your choice.
When you have all the plugs in, the cam pulse gets noisy.
I would start with sequential off, and then take a crank scope with the engine idling to check if the cam pulse is clean.
If it is, you can delay sequential injection until the cam pulse is clean.
