Just got an update. The tires made a world of difference, but remote tuning was causing issues with the variable nature of the A/F ratio and after numerous back and forths, RSI has decided to fly Jeremy to Atlanta to deal with the car hands on.

Slight update to the thread. I decided to go AEM and purchased Jrod's AEM that he had for sale on here. RSI is aiming to get Jeremy flown out to Atlanta the second week of February, so hopefully I can wrap this thread up shortly there after.

Minor update to the thread. The car made 705whp at 8.7psi according to the AEM Log. We had to stop there as we were having some issues with the AEM in regards to commanded vs actual. Hope to get to the bottom of it as quickly as possible and turn her up to 14psi.
In every build whether its a big massive build or a "small" build, it's always something. I DIY alot of my own stuff and I swear I spend more time dealing with "oh shit" and "WTF" than the actual build. I can give you countless stories just on my current build.
I went through this on my Aem as well. The boost log will only record what your load hits on the Aem load scale. If your load scales go from let's say 11psi then the next one being 15 psi and so on , and your car hits 14 psi (real time) the log will still only show you hit 11 psi because it never reach the next scale of 15psi.
The best way to make (real time boost) close to (logged boost), you need to tighten up the scales at where you plan to boost. Also run the smallest map according to your boost. I use to run a 3 bar. Now I run a 2 bar from roe. As I don't plan to boost past 20 psi.
Hope this make a little sense for you and sends you in the right direction.
Absolutely and thanks. I will let ARD know as the car is still with them. The issue we were having is we were commanding 15deg of total advance, but the log showed us getting 21deg. There was no cell even close to 21deg in that area of the ignition map. Then we logged map location versus actual ignition and it showed that we were at 15deg advance on the map, but logged timing at that point was showing 21deg. It was very strange and we are sending the logs over to Jeremy and ARD's contact at AEM to see if they know what's going on.
And yes, we did check all of the multipler tables to make sure none of them were affecting our total advance which they weren't. They were all zeroed out or at the very least, pulling timing.

Are you monitoring the EngineLoad parameter to determine load? That reads directly from the MAP sensor. It will read out to decimals if desired and has nothing to do with breakpoint scaling.
We've used 5 bar map sensors on the older Series I EMS systems and don't experience the situation you're seeing. Just a thought to try to help you out Joel, good luck!

Doc1, who has my latest front mount TT setup had the same problem with his AEM.
Larry from SP told me that was a big problem on all the older AEM ECU's like the one you have and Doc1 had.

Doc1 fixed the problem by going with a PRO EFI.
I remember talking to Robert about PRO EFI. Really cool system, but I think by the time it was all said and done with it ended up being pretty close in price to a Pectel. I think Tiago is also running this system on his coupe. Did they ever come out with a plug and play harness for it?
In the past 3 years, we have only seen 2 AEM 30-1500 units that have actual issues.
Most of the issues that are seen with the the AEM 30-1500 are actually other problems the individual cars are having. This unit was absolutely fine when it came off Jrod's car and I'm sure it still is fine. Jeremy is working with Chris to get it resolved.

This was the AEM in Jrods car and he never mentioned any issue of this and I know his car was particularly well sorted. That being the case, is the log correct or what the map is showing correct?
