How did we fix Mat Armstrong's Lamborghini?

- When @MatArmstrongbmx's twin-turbo Lamborghini broke down in Spain everyone wanted to know what had caused it. Was it the tracker unit? Could it be fuel related? The comments had a huge number of suggestions, but there was only one way to find out.
As soon as the car was back on UK soil, we got it back to the shop to investigate, and, after an hour with a laptop, we found the problem...
Pleased to say that Mat now has the Gallardo back and is looking forward to using it - hard!

That’s why points and condenser win hands down 😂…sorry Rick couldn’t help myself..detailed diagnosis superb.
Great explanation and once again showing you really know your stuff Ricky
Thank you!
What a belting video. Really appreciate these videos. Fascinating to see what was wrong and how it was diagnosed. 👍🏻
Thank you Dave!! 🙌🏼
That was quiet fantastic Rick. Being a computer guy for 30 years. I appreciate that applied level of engineering. I’m all over my cars now with diagnostics tech and see the who’s who’, the what’s what and the when’s where with it all on how they’re running.
Had an issue with my upgraded RB26 AEM CAS disk… ended up with the oscilloscope out and found out that both the ref and sync rising edges were happening simultaneously - causing a trigger issue at low rpm. Changed it to a falling edge ref and so far so good! Funny your vid came out the same time I was sussing mine! Good stuff!! 👍👍
Good find mate!!
Wow, absolutely amazing, well done fella.
Excellent video Ricky. No parts cannon trouble shooting at REPerformance 👍👍👍.
Thanks mate! Giving away trade secrets lol!
Nicely done Ricky and you well explained your thought processes and how you went about identifying and sorting out the problem
Thank you! Glad you enjoyed it.
More of these please Rick!!
I liked the detailed analytical process you stepped through and demonstrate your method to solve the issue. thanks for showing us the tool set and logic used.
Very welcome!
I used to work with Volvo trucks. If the ECU didn't see a cam sensor signal during crank it would fire an injector every 360 crank degrees and watch for the rpm to kick to work out where it was and then run normally after that! So if you had a truck that had to crank for a longer time than normal, it was a good bet to start looking at the cam sensor. Don't know if cars do that though!!
WOW!! Thank you :)
This explanation is why vehicle techs deserve a hell of a lot more respect for what they do and know.
Glad you liked it!
Great video you obviously know your stuff 👍…I didn’t understand any of it 🤦♂️😂
Don’t tell anyone! We don’t either! 😂😂
What a fabulously detailed video Ricky…and on a Friday evening when many will be down the pub….now that’s commitment 😅
Glad you enjoyed it!
Nice vid 👌
Cheers mate!
Great insite in what a crack sensor needs to work, explained in a way that made it very Understandable.
Now I understand what went wrong on my Audi S4 B5 when crank sensor failed on that, and yeah was a twat to change. Great video as always . Thanks 👍👍
Thank you!
Super interesting!
Thank you!
Amazing work. I am seriously considering getting my Gallardo TTurbod with you guys.
Thank you! Here when you need us!
I’ve got a Vauxhall Combo Van and does a Crankshaft Sensor every few years what a pain just for a small part
Yes, is a pain especially as it just kills the engine!
@6:55 you said you don't do a "monkey diagnosis" but sounds like it would have worked this time! 😉
Money diagnosis will always work, it’s just how many times you have to buy expensive parts to swap out.
We just like to prove what it is with diagnosis before we change anything. 👍🏼
Love this stuff ❤
Thank you. Glad you’re enjoying the content
Interesting stuff, great video and shows how technical it is 👍🏻
Thank you!
Great info, yes I seen 1or 2 guys guess crank sensor. I remember I had to change one on my sons 1st clio car. 😂😂😂. Great explanation, learnt alot there. 😉🥂🥂🥂🥂🥳🥳🥳🥳🥳
Thank you! Glad you enjoyed it! Yes not many things stops an engine dead and they are more common that people think!
I was one that guessed on matts channel 🤣 joys of working in a vw dealer
@@salkeld12 the burden of knowledge! An informed shout btw!! 🙌🏼🙌🏼
Could you not have used state of change verification instead of or before overlaying the signal return?
Yeah I haven't a clue what all that was about lol, I think this stuff is a little advanced for me
Awesome talk thru, I was one that said Tracker at first, just because of when the issue started if honest.
I did thank that too to be honest!
What??? This is clever stuff way beyond my capabilities. Amazing
Thank you!
Surely you belong in F1? your skill is brilliant.
Nah, spend your life locked in a garage. I’ve worked in the bike racing world for long enough….it’s glamorous on the outside! 😂
Love the video
Thank you!
This man is a Legend,!!!!
Thank you!
Hi really enjoyed the video. Can I ask what fails inside the crank sensor to stop it working?
Another world !! Lol
Would it be impossible for an ECU to use a crank position sensor (s) to run the engine in a limp home mode. ie it recognises the loss of crank sensor and then when cranking shuffles through the sync options until it see's the engine start. A bit like back in the day if the distributor was loose someone could crank the engine whilst someone else turned the distributor until it fired.
So certain ecu’s can continue running if they lose one of the signals. Some ecu’s can start after a long cranking period if they lose a cam signal (they just batch fire until they see rpm flare) but on stock R8/Lambo ecu’s or the syvecs they won’t do anything without a reference signal.
Please do more like this
We will try!!
Scope on the crank sensor would have been a handy test
Syvecs has an inbuilt scope, that’s the ref/sync capture I show.
Is this similar to a phonic wheel ?
Same principle but a phonic wheel passes a magnetic sensor to generate a voltage which is interpreted by the ecu. These Hall effect sensors have a small chip inside which essentially ground the signal hence the need for 3 wires (5v, gnd & sig) whereas a mag sensor is commonly 2 wire.
Who's matt Armstrong? And why is that relevant to the title? 🤷♂️
Because it’s his car….
he's a RUclipsr, and it's *Mat* with one "t"
No idea lol
Furst
Hahahaha
