I hope for the best, but as enriquez has said, if the previous tune wasn't spot on, you will be messing with more than the data sheet settings. And that means even if your commanded and actual AFRs are perfect, but that is a result of two wrongs (fuel settings and VE settings both incorrect)...
I think in this case, assuming the car was really dialed in before the injector swap, the FIC data should be enough to get the car back to where it was. The data sheet includes all of the dead time information across the voltage range. The very specific fuel flow characteristics etc. But if the...
Step 1 of all wideband gauge/controller vs. ECMLink logged value investigations is verify your positive and negative wiring for the gauge, as Curt mentioned above. If the AEM controller and ECMLink don't agree on what 0V is, you'll be chasing your tail on this issue. Make sure they are both...
"Displayed" values and "Captured" values are two different menus. You need to "capture" CombinedFT (or more precisely its component parts) before you can "display" it.https://www.ecmtuning.com/wiki/ecmlink101datalogging
This covers essentially every boost control configuration you would ever need to consider and the benefits of each. See if this clears up your questions.
I have a 2G. I had to swap the MAP sensor from the Baro input that ECMlink uses through the factory MAF connector to the MDP input that would have been on a factory 2G car. I have also found that the PnP adapter default tach output seems to cause a very jumpy tach so I need to troubleshoot that...
https://www.fs.com/c/copper-patch-cords-960This vendor is favored by many of the 'homelab' YouTubers and Subreddits. Mostly for the optical stuff but they have a large selection of copper stuff. Might be worth a look to compare.
https://www.dsmtuners.com/threads/e85-injector-max-lb-min-calculations.253452/Take a peek here for fuel Injector sizing questions when moving to E85. The fuel injectors/pump may be the one other area of focus when swapping to a flex setup.
With the sensor installed directly into the intake manifold, thus no rubber vac line to act as a filter, I wonder if the pulses of intake air are causing the jaggedness you are seeing. The intake valve events mean the intake manifold isn't at 12 psi flat all the time but is actually jumping up...
UPDATE #49 - 12/4/2022 - Interior Trim Refresh/Haltech First StartFinally took care of a few interior trim issues that have been lingering for years.A-Pillar trim piece has had a hole in it for the previously installed gauge pod.Driver side mirror trim has been missing a section. New one...
