We have a little Porsche build we did, I’m unsure of a few little settings though before I start the engine.

So far:

-We changed the linearization to NTK wide band l2h2 for both banks.

-We changed oem linearization on the MAP sensor to an 3.5 bar sensor.

What we are not clear on how to perform a few functions, or if there is anything we are forgetting...

-Is there a VE calibration to change the motor from 3.6 to 3.8 liter?

-Changing from the factory 440cc injectors to Injector Dynamics ID2000’s, not sure what tables need adjustment to rescale these?

-We removed both the factory MAF sensors and need to run speed density. Unsure of what to deactivate or adjust to make this change?

-We also are unsure how to enter or change base files 5bar fuel pressure. We are running a boost references fuel regulator at 50psi engine off.

If you could give me a list of what tables to adjust for each of these that would be so helpful. We would really like to start this new build for the first time. Below are our builders specs, Thank you

Syvecs is a time based injection model, it’s not a VE based ecu, so a lot of the points you have raised above won’t need to technically be done.

For example, you don’t need to enter injector size, you will scale the base fuel injection time yourself under Run Mode > Fuelling based on the increase in injector size if you’re using a basemap for a stock injector. Naturally you will still need to enter the deadtime data.

Have you watched Andres Syvecs practical example? It will no doubt help you.

Same point applies for engine capacity, you won’t enter this, you will calibrate the necessary maps to account for the increase in capacity.
