Porsche Boxster 986 - engine swap project
Discussion
I'm leaning that way, I've done some tests the ECU isn't damaged. I've got VCDS which is the popular VAG diagnostic software, it can log all the sensors, the ECU can read the pedal sensor which is good news but the values are way off. I need to compare the values with my mates S4. Hopefully it'll be something that I can adjust on the software.
I'm chuffed to see this build has made it to the front page of Pistonheads, seeing that was a nice surprise. Thanks for that.

Pretty sure pedal values should just be 0-100.
I had a look at my mates S4 tonight and the values are 15% off the throttle and 80% full throttle. I've got a plan on to get this working. benillsley said:
Any reason you decided not to go for an after market ECU to run it? Cost? Or just because the standard kit is more than up to it?
The development done on the standard ECU is impressive so I don't see much of a benefit in going standalone at this point when you factor in the additional costs, although it isn't something i've completely rule out.I've only just picked up on this thread OP, it is just incredible. For the first time in my life I'm going to use "awesome" as the only worthwhile adjective to describe your vision, ambition, prowess and determination. I have no idea what you do for a day job, but if this thread doesn't get you a job offer from Frank Williams or NASA I'd be amazed! Well done Sir, keep it up, can't wait to see the outcome.
Well I'm glad it made front page of PH too - as I've just had a fantastic massive mug of tea sitting down and reading this end to end!!
Superb - that is multiple pint-buying-worthy all day long!
The summer is totally cr@p anyway - I only took my 944 S2 Cabriolet out of the garage last week for the first time in over a year, to try and enjoy a few days of open air fun, it's already ready to go back in again, so don't worry about missing Summer........ there are plenty of clear, bright and sunny days over winter ya know!
You can't let it get on top of you now....... you've made front of PH........ now we're all depending on you to get it done!! Hahaha!!!
Just love it, I love the engineering, the logic, the industriousness, the resourcefulness and of course, the epic determination. There will be many out there who just won't get it, who just won't understand why. But they are not people I really have time to be associating with: if they have to ask - they'll never get it.
Like the question as to 'why climb Everest?' 'Because it's there' is an answer that makes damn perfect sense to the rest of us!!
Keep it up man, like everyone else, can't wait to hear and see it roar!

Great thread, great build, superb work and engineering, kudos to you sir, very motivational.
I will get around to building something someday, when I eventually get a house which has a nice big driveway and a garage! Until then I'll just keep spending my money on ///M cars and beer, the rest I waste on family, and bills!! Lol

Thank you all for the positive comments, I appreciate them, they are good for morale while i'm grinding away doing the boring jobs.
I recruited some help on the wiring.
The Audi fuel pump relay also provides the power supply for the lambda sensors and injectors, I had these circuits wired up on separate relays but i'm getting a fault code on the fuel pump relay as well as all the other fault codes so have decided it best to re-do it. My mate picked this up for me from the scrappy as I didn't have the foresight to remove it from my A6.

She's the master tech, i'm just the labour.
The Audi fuel pump relay/distribution block fitted a treat on the Porsche relay holder which has helped keep it all neat and tidy. Everything has been wired up.
I got it started. Lots of the fault codes have gone. I've still got a temperature sensor code and the throttle pedal ones but otherwise i'm just left with the ones I expected now that will be coded out. I took a little video of it running. There is an exhaust blow on the v-band from the turbo plus it's in the car port so hopefully it won't be too loud once that's all sorted.

It made a bit of a mess.
