Yes, both AFM and MAP fuel tables need to be checked.

BTW I'm still waiting for the verdict on non-speed density operation.

I've got an RDX on the dyno right now that I'm hoping to build a speed density file for.

We're going to see how nice it plays.

Speed density fueling works, but I have some notes regarding it.

What email should I send them to?

Thanks!

Any chance you have looked into pid control of boost and a cel kill for maf voltage yet?

I can supply a data log that shows a really bad ossilation if needed.

I am also curious as to the status for the AFM over voltage code. Looking to upgrade my turbo but won't be able to without this ability.

AFM maximum voltage is already set to 5V for all RDX models. If you have an error code, let me know the code and what vehicle you have.

The code that's being set for the MAF voltage is a P0103. This is the same code that's being tripped for all 07-12 RDX's.

If you tell me what vehicle you have I can implement a fix for that vehicle so you can test it.

Same thing for me. MAF is throwing P0103. It's holding us back from like 5 more PSI, and tons of HP and TQ left on the table. We need a way to disable this code asap! Really disappointed in how something so simple holds us back.

Speed density fueling, stock-sized MAF housings, and the MAP-based WOT determination features are working flawlessly now on a handful of my clients' cars; the transmission's shift characteristics have greatly improved, but as others have mentioned, we are limited by the MAF's P0103 code.

It is indeed a bit frustrating explaining to the customer that the software has only been half-fixed in regards to these.

Being one of the ones who really pushed for speed density tuning, were happy to get it and that it works however without either raising the max voltage for MAf sensor or simply disabling it we are held back by this. Setting the MAX voltage .5 volts above stock is simply not going to work so we need 1 of the 2 options above which i know are simple for you to change for us. Thanks.

Yeah we got to get this going more of use are trying to make more power in these rdx for 07 to 12 . More of use have 07 to 09 rdx sh awd . So we need to do something about it . We want to run down some cars that think they are fast then us it's nice telling them u just git ran down by a 4 cylinder Turbo. So we need to make more power. So please get on the ball in fixing are tuneing software so we can
