Yet below, you said it did.
So it kinda sorta passes?.
No CCP control
No EGR

Please explain how, it could function any better?.
Since you've pointed me out.
I have the proper drivers for the P+H injectors, and a lean cruise.
Now to split hairs, I have a Translator Plus so I can change timing on the
fly, and fuel on the fly without even needing a laptop.  With my  Scanmaster
I can monitor any parameter on the ALDL link.  With my Direct Scan I can
record 18 frames a second, if I want to hook up a laptop for datalogging.
Also, a boost controller for on the fly wastegate control.   While to add
them all up gets into some money, but I've just done one at a time as funds
permit.
I can run closed loop, open loop, open loop idle.
Anti-theft, launch from stand still rpm control.
Control the CCP, EGR, TCC.
Can do the catalytic converter rich lean cycle.
I can run my version of antilag.
I can trim fuel by TPS or VSS
Prior to getting the lean cruise, in normal driving got 25.6, and that
included some fun moments.

It's acceptable, but what's your point?.
Speedpro has it's place just as well as others do.  But it's no miracle.
I just took exception to your statement of in 30 mins could out perform a
oem ecm.

An abbreviated one.  Just no way for it to pass the full oem testing the EPA
requires.

>Could full time closed loop really work?

Of course, Honda has been doing it for years, and with full emissions
compliance.

You're the one that made the claim.

You got a race car and the bucks, a SpeedPro can be a nice ecm.
Want to run P+Hs for port injection, it's one of only a few that can.
Simple laptop programming, again fine.

> Yeah, I know, you meant to delete this offline...

Na, you missed the point on when I use that remark
