What is the plan to measure engine load for the ECU?
Has that header been run before? If so how did it fare up to say a MSS?
Yep, I have an ITG filter that fits right on that. For ecu load I did build a small vacuum log with 4mm tubes from each runner linked together, but I do have my doubts on how effective that will be, I am thinking that primarily the maps will need to be TPS biased.
Why do you suspect the MAP will not work well? Too much lag, bad average across the four ITB? The alpha N just seems too far removed as an inferred engine load.
From talking with others that have done standalone with ITB's , the map signal ends up not being that useful in tuning other than in idle , after that it's pretty much atmospheric pressure all the time. That said, I'm sure that trionic can be made to work well, I think its just a matter of some time spent tuning it... I also have the electromotive system in case the trionic does not want to play nice.
The engine is now in a for a test fit - no clearance issues with the intake, filter, alternator relocation or the exhaust, so that's a big relief. I also easily adapted the exhaust manifold to the downpipe. I probably need to build a different coolant reservoir that mounts further to the rear to better route the coolant into the water pump since the air filter is in the way of a nice direct path now. I laid out the trionic loom from a NG900 and because the TPS is actually closer to where it would be in a NG900, the lack of turbo-stuffs and ability to easily go through a hole in the firewall, I won't need to cut even a single wire on the loom to hookup!
I still need to convert the car back to EFI pumps since it was running carbs most recently. Mechanically, the car just needs a solid weekend of work to be a runner. After that it will just be a matter of tuning.
