You're a lot more realistic setting hours for repairs.
I was so far off I gave up putting times on mine.

Glad it's a shorter list...

When my list is that long I just go do something. You just made a huge elephant that's going to take fourever to eat. If I thought that far ahead I would never get started. I have no plan or direction, I just turn wrenches.

But that's just me.

Are you using the new plastic back pad from 914rubber or using the OEM cardboard. If the plastic one, what were you quoted? This info will help me decide if I want to be an upholsterer or not. (IMG:style_emoticons/default/biggrin.gif)

I havent bought/tried anything yet. I have a feeling Im going to make something out of fiberglass as I'll need to make some considerations. Not sure. I'll probably do that next year (IMG:style_emoticons/default/smile.gif)

Progress!

Drove it yesterday! If your at all interested in a 5 min video of the sky and 11minutea of me looking around and diagnosing stuff your welcome to watch (IMG:style_emoticons/default/smile.gif)


https://www.youtube.com/watch?v=U2FqsUZ5pW4


In short.

The good:
The new trans shifts like a boxster, buttery and amazing.
The steering system feels fantastic.
The engine runs just like it always has.
Chassis feels much stiffer with the steering system improved. Feedback is much better.
Dash has a very usable layout.

The bad:
First gear was difficult, I didn't have enough throw in the shifter to engage it. A little 20second shifter adjustment and I think that's taken care of.
AFR guage needs calibration
Intercooler fan controller isn't working for some reason.

The Ugly:
I warmed it all the way up and tried restarting. No avail even with my modulating or full throttle work around. I let it cool down some and took some video of it struggling to start and what I was doing with the throttle to coax it to start. Myself, my dad and my tuner think it needs more fuel. My tuner says it has two fuel maps, one for enrichment and one for normal operation. He says we can add fuel to make it right. I'm going to get some starter fluid and see if adding starter fluid helps the hot starts. If it does we finally know what the problem is and can correct it.


I have a Dyno day I'm working on scheduling before WCR so I can get a bit more torque and clean up the map just to make sure I have my basis covered.

Yeah that is so WEIRD. Seems like it has to be fuel since you replaced almost all the senders/sensors. Normally I would say temp sensor but I think you checked it already. It would also likely be easier to start when warm vs. cold with a bad or miswired temp sensor. Sounds like you have the opposite problem. The starter fluid is a good idea.


Nice work on the new steering setup. Love the dash. That's going to be really nice.

Starter fluid works.

More driving around video and me trying out the starter fluid.

Are you losing fuel pressure when the car is off? Takes easily 2-3 seconds to build pressure with the pump on the other side of the car. Your cranks on film are too short.

BMW and likely a few others (like your Infiniti) actually trigger the fuel pump when the door is opened or other sign of pending use, like the remote is nearby, say in my pocket, as I replace an injector... (IMG:style_emoticons/default/dry.gif)

It would also likely be easier to start when warm vs. cold with a bad or miswired temp sensor. Sounds like you have the opposite problem. The starter fluid is a good idea.

It's not an uncommon problem actually. You typically have a one time starting pulse adder which is a function of engines temperature and also a startup enrichment table with pulse modifier which is on a temperature vs. crank number table. If you taper off too fast with temperature you can have issues. Sometimes, people also have the thresholds for starting engine speed too low so they car starts thinking it's running when it's cranking really fast and doesn't get any extra fuel. Lots of little nuances can cause a lack of hot start fuel unfortunately.

Hope you guys figure it out soon!

Pump is literally next to the engine, and it's an 044.

I've tried letting it build pressure with no avail and letting it crank for a minute with no results. Audi kills ignition on cranking after 5 seconds.


JD is correct my tuner said the same thing. It's going to take some time to figure out but we'll get it.



Also quick note, I am running 1300CC injectors, so I have a strong feeling with them being so large its compounding this start issue.

Hot Damn! Way to go. Why didn't Mike encounter these problems. Is he running an aftermarket ECU?

Are you sure you're getting a start signal to the ecu? Usually it triggers batch fire as the air isn't moving fast enough for sequential to work right.

Injectors timed to spray into OPEN valves? 1300cc is going to have some latency.
