    Tuning at streets of willow 


    It’s a bit hard to take pictures with an iPhone, strapped into a 5 point harness, carrying a laptop with helmet on in an exige. But try doing test and tuning on streets of willow with the same setup !

    Here are some of the cars at LCS I’ve worked on.

    Hacking a Porsche Cayman S 


    What other line of work do you get to do bad things to expensive cars? Well quite a few now i think about it. But still, hand soldering a meritec PSOP44 (which you’re not supposed to do, float/wave only!)

      Nice work there, found you from hackaday! … starting to get into ecu hacking myself, though am lesser even than a plebe. You said “i make commercial ecus” … would you please email more about this?

      Are you working with a vendor for the production — meaning the connectors and drivers? Are there specific applications they are focused on? Do you know of means to reverse engineer marelli, continental, and mitsubishi ecus? Those are a couple that come to mind… 🙂

    Testing a new A2A intercooler in Death Valley 


    Just a couple of snaps of the “Google says that is a road, it must go somewhere, right ?” or the why can’t a car that is basically a plastic track car with sports suspension made by neep farmers in southern England not be able to handle a bit of off roading.

    Lotus tuning, 318RWHP SC Exige and 265RWHP 211’s 



    Out to Indiana, with a cool looking DynoJet that had a platform lift and a big cage, fun trip, even the 13 hour trailer drive to Maryland after!








    Street tuning with a light car, with street legal slicks and the rain, not fun.

    Wiring up a Race Technologies display 


    I did this one a while ago, it was not a fun project! After getting it all working, programmed, new firmware written, and mounted, the Dash unit failed first time on the track!

    Lotus tuning trip number #74328432 


    headed off to Tripoint Engineering in Canoga park to finish up a car that had some issues mechanically, the harness was incorrectly reinstalled after some work and was causing the VVTli to fail to engage sometimes.

    Spent 3 or 4 runs with it and it achieved 244RWHP , not bad, forgot to grab the dyno sheet though.


    Forget to take pictures of it on the dyno, but finally did remember to bring the Motec with me, transferred it to a friend who’d drop it off to the owner at Laguna Seca, of course he forgot it at R3 and had to go back and pick it up, comedy of errors that dash.

    Then i headed off to R3 Motorsports in Van Nuys to do a couple of NA Cars.




    These two I’d done before.

    Another car with a P0172 system too rich showed up for a quick diagnostic, as usual its a 95% a vacuum leak.




    R3 do the Ferrari Challenge series, a few interesting cars around. Forgot my camera so the useless iPhone is my only one, even though my n95 languishes at home.



    But by an amazing coincidence, on my recent trips back to Los Angeles, I’ve kept forgetting to swing by EdSyn for some spare tips for my soldering irons, their website is frankly horrible to work with, so I prefer to shop there. When i pulled into R3 i thought , i know this street!, and sure enough they were only 433 ft away, so i popped in while waiting for people to turn up, saw a couple of hummingbirds.



    neato! same exact feeder i used for my old webcam coolpix 990 usb controller program too, it took a better shot though, I presume its a different bird though, since its been 8 years or so.

    EdSyn had a new display and shop too, and they’ve got a sale going on for 20% off.



    Lots of tips and bits.

    I picked up the vacuum pickup tool that converts my 1036 into a 1036DX, i find the simple suction hand pickups just don’t work that well.

    All in all one of the easier trips I’ve been on, though its a continuation of a trip that didn’t go so well, so still have yet to do a simple in and out.
