gdog Posted July 15, 2019 Report Share Posted July 15, 2019 Awesome results! Wasn't sure what you meant by "synch loss" but then found this link: https://www.diyautotune.com/support/tech/other/megasquirt-vr/ Now I see. Good shielding on the VR sensor?

Kevin. Posted July 15, 2019 Report Share Posted July 15, 2019 you gonna shave yet? congratulations dude, you now (probably) have the most powerful P80 in America Quote Link to comment Share on other sites More sharing options...
B_Dub Posted July 16, 2019 Report Share Posted July 16, 2019 That’s just nuts, so stoked for you! There’s so much room to go on your setup, can’t wait to see you turn the wick up, big(ger) numbers to come for sure! Awesome work! Quote Link to comment Share on other sites More sharing options...

gmsgltr Posted July 16, 2019 Report Share Posted July 16, 2019 Just watched the entire video - wow The dyno paperwork says you have a 4cyl haha 😛 Also thought it was funny the habit of putting your seat belt on when you got back in once to dyno haha then you quickly took it off ^im only picking at you now because, well, you have a 600whp t5r!!!!!!!!!!!!!! congrats man - i bet this feels really good after all the hard work and unfortunate set backs along the way Quote Link to comment Share on other sites More sharing options...
Commander Riker Posted July 18, 2019 Report Share Posted July 18, 2019 Probably one of the cleanest high power builds I've seen ever. Thanks for putting so much about it up on youtube. Have a lot to go back and watch. Quote Link to comment Share on other sites More sharing options...

The issue actually ended up being too big of a shunt resistor (resistor wired in parallel between the + and - leg of the VR sensor. The voltage was getting too high at high rpm and the decoding circuit would overload. I switched from a 10k to a 3.3k and it has solved the issue (atleast on the street). This will 1/3 the voltage.

I work remote for my company, so gonna keep looking like a bum. 😂 On 7/16/2019 at 1:26 AM, B_Dub said: That’s just nuts, so stoked for you!

Yeah I kept doing that. I would throw on the belt and be like wait wtf am i doing. On 7/18/2019 at 10:43 AM, Commander Riker said: Probably one of the cleanest high power builds I've seen ever.

I really want to try and take the channel to the next level. Theres SOOOO many Honda, Toyota, Mitsubishi, Supra, BMW channels, its time for a legit Volvo one.

Seems a zener would be a more appropriate solution, no? Thinking two zener diodes back to back (maybe a resistor in between) across the VR sensor leads?

Thinking two zener diodes back to back (maybe a resistor in between) across the VR sensor leads? I don’t think a zener diode would work. That would actually clip the AC sine wave. I simply want to reduce the amplitude. A resistor across the VR sensor lead works fine, you just need to choose the lowest value resistor that doesn’t give you problems at low rpm. I was running too high of a value (10k). Switching to 3.3k 1/3rd the amplitude and fixed the problem. Quote Link to comment Share on other sites More sharing options...
Simply Volvo Posted August 5, 2019 Author Report Share Posted August 5, 2019 Fixed my sync loss by changing the value of my shunt resistor and also finally tuned ignition timing. Session got cut short due to t bolt clamp failure. 1 5 Quote Link to comment Share on other sites More sharing options...

tuner4life Posted August 13, 2019 Report Share Posted August 13, 2019 This is so cool! Awesome to see the power getting put to use, not just generating dyno numbers! Quote Link to comment Share on other sites More sharing options...
