Post your ITB Setup

[SiracHaile]

I designed an adapter plate to mound a DBW (Drive By Wire) actuator for my Clewett ITBs

I made some fiberglass stacks with ITG dome filters for my 2.7 MFI motor.

That's very nice! For my setup, my engine tuner recommended running one DBW servo per bank. I am using AT Power ITBs. He also recommend using the throttle position sensors built into the servos instead of using throttle position sensors on the ITBs. Here is what I ended up with and it works quite well:

Running two actuators is better for a few technical reasons, but neat to do it with one! Less is more sometimes

Love to see the different DBW setups, so much you can do with DBW

Awesome! 906 is one of my favs.

Need these for my 3.2 SC. What's the whole setup you recommend? I'm an unmodified 930/20 motor.

Another x-faktory kit .....WIP......this will be installed on a 3.0....the ECU for the system is a Link Storm, Clewett crank trigger, sequential.......complete custom wiring harness by Dennis Powell

Awesome thread. Going with EFI on my Beck 904. Using a short stroke 3.2 as my base and a fully built 901 side-shift trans from CMS utilizing a wavetrac LSD. Still trying to consider the EFI setup and cam choice for this. I want compression to be at 10.5 to 1. Haven't decided on DC-80, Webcam 993 Super Cup etc. Still working out those details.

@SBell nice looking stacks. Mind sharing details of your process in making them?

Oooooo those stacks with a filter are GREAT!

I've been meaning to make a thread on how I did it. I'll try to get around to it this week. It did require a lot of specialized tools (CNC & lathe) but happy to share.

Here's the link to my post on Al's thread on the engine forum https://forums.pelicanparts.com/12108561-post20.html

I installed it last winter using Al's RHD kit suited for EFI conversion and I added in the full sequential controls for injection and spark with COPS. This setup is about a 23% increase in HP over factory specs.

For this winter, I've ordered and received William Knight's M1 cams along with Ti retainers and Aase springs. I'm just about to start that job once this current cold snap subsides. If I find broken head studs this project will snowball...

Hello everybody!

I'm new to this forum and have some questions about tuning a 2.0 911E engine.

My dad and I are currently working on our friend's car, a '69 2.0 911E which was originally fitted with mechanical fuel injection. However, the mechanical system proved to be quite challenging to tune as it would run poorly when tuned for cold starts and vice versa. So, I suggested transitioning to a standalone ECU. In this case, we opted for a RusEFI / FOME Proteus ECU.

We endeavored to maintain as much of the original setup as possible. We mounted a Triumph Daytona 675 throttle body with a custom 3D-printed intake manifold to the original air filter housing.

We managed to get the car running and driving some time ago. However, last week when I fired the car back up, it was running excessively rich (9-11 AFR). It's worth noting that the air temperature was about 10°C lower than the last time it ran. Despite my efforts, I couldn't get it running smoothly until the oil temperature reached at least 50°C.

I would appreciate hearing from others here about their experiences with idle tuning and dealing with temperature changes. I've heard that Individual Throttle Bodies (ITBs) can be a bit tricky to tune for idle.

Due to the ITBs, I'm currently running Speed Density with TSP override. This decision was made because the MAP values are around 70 kPa at idle, which is less than ideal.

Excellent! Thank you for posting.

Krakert......I'm not familiar with the Rus/EFI Proteus, but it looks like TunerStudio is used .....have you been data-logging? If so...email me a copy of your logfile (capturing the cold start up through the temp rise when the oil reaches 50C) I can review it to see what your AFRs are during the cold start and how your tuning transitions from cold start thru warm running. As you know there are several cold start fueling steps....Prime,crank, After-Start, Warm-up......

I would also recommend that you verify that the ITBs air-flow is still balanced and that the temp sensor, map sensor etc are all working properly....

Well they actually are being used as TBs as no fuel goes to them.

Very cool setup, Ben. Did you use Jamie's fuel line/injector kit?
