  1. yep the firing order is correct, and I tested all of the coils. Firing on the correct cylinders. this is a 6.4 liter 32 valve 90 degree V8, with some really lumpy cams. It has 8 50mm ITB's and I haven't gotten them sync'd yet, and I haven't had time to get back out in the garage after getting it started.I just adjusted the throttle stops so it would idle without me holding the throttle open. I'll have to get the idle bleeder screws scync'd and the linkage as well, I also need to dial back the dwell on the COP. as it is using the standard table. Do you have a screen shot or a table I could import for the dwell table? I also downloaded a table for the ID725 injectors but my ecu won't let me import it stating it is locked for another ECU. I think I downloaded it from Injector Dynamics. any way to get them unlocked? ShortPulseWidthAdderID725.lte INJDeadtimesID725300kpa.lte
  2. tomorrow I'm going to move the base timing back to -58 as I think the failure to start was the fuel pump relay shutting off. Then I'm going to isolate what is backfeeding the starter relayl
  3. I set the priority to trig 1, and set the trigger offset to 302 and it kept dying on start. I finally bypassed the factory fuel pump relay and she runs~! runs rough and rich but it starts. I just have to figure out how to use the factory relays.
  4. updated firmware. I could have sworn I had trigger 2 set as hall. I looked and you are correct. Trigger 2 is now set up as hall. pullup resistor on . Here are the latest config, log and scope files. Should trigger 1 or 2 be priority? Trigger Scope Log 2021-08-3 6;58;22 pm.llg Log 2021-08-3 7;03;57 pm.llg 7PM 8-3 config.pclr
  5. I'm seeing 4.2 M ohms between pin 2 & 3 on the cam (hall) sensor swapped wires on trigger 1
  6. trigger 2 is a hall sensor on the cam see above post
  7. so now I'm seeing trigger 1, but nothing from trigger 2. Trigger Scope Log 2021-08-3 4;50;40 pm.llg trigger 2 is a Porsche 944 hall sensor (the 928 shares the same sensor)(944-606-170-01)(Bosch 0 232 101 013) What I have for wiring is: Pin 1 +5V, Pin 2 signal Pin 3 sensor ground
  8. ok so that is what I did. started the capture and then started cranking. I will get a new capture shortly
  9. I don't seen any wave on the attached logs so am I correct in assuming I have a wiring issue? Trigger Scope Log 2021-08-3 7;32;41 am.llg
  10. when you say add 50% you are saying the master fuel trim correct?
  11. I was out setting the base timing. I don't have a timing light to set it the correct way. I've got a pcl file from a running 928, so I think the correct timing is -58 It sounds like it is really trying to catch. do you mean a trigger scope from the link software?
  12. I'm running ID725 injectors, and found a couple of tables I wanted to add to my config but found out they were locked. I also know I need to adjust the dwell settings on the coils, but I don't know what a good table looks like for my VAG coils. Any info on either would be appreciated even if it is a screen shot of a good table. I can get it entered in.
  13. I'm trying to get an initial start after setup and I'm missing something. I'm having issues getting the right starter input and output working properly so this was with a bump starter. It sounded like it was close on a couple times. Fuel pump would shut off, during the cranking process. Not sure if that is normal Log 2021-08-2 8;40;41 pm.llg traditional model almost start 8-2 8-39pmcst.pclr

    LSU 4.9 question

    On the left is the connector I’m talking about and the one on the right is the connector I want to replace it with.

    LSU 4.9 question

    I’ve attached photo’s of the connector on the sensor

    LSU 4.9 question

    The LSU 4.9 that I have from Ballenger has this bulky connector requiring a rather large hole through the firewall, In talking to BM, I was told this was for ecu's that can't do a free air calibration. Did I buy the wrong O2 sensors? Can I de pin and put the smaller standard LSU 4.9 connector on it and use it that way? I'm not that experienced in the newer wideband sensors.
  17. I've been reading on a lot of forums that the coils have 2 grounds, and here on the link forums I was told to ground both grounds to the cylinder heads, but I've been reading that you are supposed to wire one of the grounds to the sensor grounds. Which one is correct?

    Thunder Temp3 input

    Thanks for the quick resonse Adam. Mike and I are rocking along on our 928's thanks to you~! I'm shooting for a thanksgiving start up. The last time the car was on the road was 2009.~!
  19. about 2 minutes and 25 seconds into this video
  20. is this also for the Thunder?

    Thunder Temp3 input

    on the Thunder, I'm using the Bosch PST-F 1 for temp 3. Do I need an external pull up? I've seen references where it's needed and then seen other places where its not needed.
  22. I'm adding this here, because I posted on Facebook but that is a horrible place to keep technical info because searching for stuff even a few weeks old is difficult. I asked: what is the consensus on using the ABS sensors for traction control? ECU is Link Thunder, and it would be preferable to not interfere with the ABS system. Adamw: The Thunder differential DI’s 11-16 are specifically designed for tapping into ABS signals without upsetting the ABS. Assuming they are common VR or hall sensors (not magnetoresistive) me: Front ABS sensor is the same as the Porsche 944 and 968. This is for a Porsche 928. They have a metal shell on them which on the below link indicates they are passive. https://www.apecbraking.co.uk/.../Techni.../ABS-Sensors.aspx Adamw: The 928 Front sensors will be VR Me: rear abs sensors are the same as front just different wire lengths https://www.boschautoparts.com/en/auto/adas/wheel-speed-sensor?partID=0265001118&fbclid=IwAR1GqYZhpppJI2yvq8NACCadDZUX2qlIH90qcQ2H1zIwqv1SDqVoc2vQ_iQ I wanted to post this here so that others can search and find this info. additional follow up question. for a VR sensor would we use the DI positive or negative inputs for the Thunder ECU?
  23. I'm using the VAG Bosch Coil 07K905715G I'm planning on using the following wire sizes power positive(12v+) 18AWG TXL power ground 18AWG TXL ecu signal (5v) 20AWG (Link Harness supplied) signal ground 20AWG TXL This is for a NA 90 degree V8 with a max RPM of 7500. For power, I'm planning on running one 14AWG TXL to each bank ( approximately 48 inches from relay) and then split out to four 18AWG TXL (lengths ranging from 12 inches to 20 inches) This is my 1st foray into coil on plug so I don't know much about dwell, current & current draw. I found quite a bit of info about calculating the current draw but I don't have a scope.
