Doh! That's right... what a shame. I found out that there have been several firmware updates for the e-manage ultimate. Two of them included specific updates/fixes for 13B-REW and 13B-MSP. I noticed that the US/English site does not include any of this information... it's on the JDM site which I linked to in my thread on this. I'd be nice if the damn thing actually worked correctly now for the RX-8...

I've got the newest firmware installed, but I haven't had a chance to test it out.
I'll probably play with it next week.

OK. Done chewing.

I am going to have to question some of Tim's math on this.
Those those formulas work in theory, but the reality is that the OEM PCM does not run the P1 and secondary injectors anywhere near 100%, even under full load.
In fact, my recent datalogs show it to be around 65% max.
I've started to invoke the add-injector map again in my tuning. It allows for some finess in the high end and at the torque peak. It will also smooth the transition into low-load, high RPM.

Again... it'd be nice if it worked this time. But then it looks like Cobb is working on a ECU flasher for the 8... which is even better.
