do you mean 1.024?

you might want to raise this to 1.1 - i doubt injectors that big can drive down reliably below 1.05ish...

that probably why you are getting afr swings..

unless you running OL..

I'm certainly not idling in open loop

My plan of attack shall be..
Lock fueling into OL, tune the OL first.
Then enable the CL and adjust the minimum IPW to desired idle quality...

and probably raise my idle targets to just over 1k rpms.

I'd like for the CL to work...but we shall see.

I'm looking at the last ROM you sent to me (Oct 31), and it is set to idle in OL.

ORLY?

I guess I'm misinterpreting the open loop enable maps. Is my mistake in assuming that them being populated with values greater than zero for TPS and greater than 60-80 Load in the 500-1500 rpm region?

My understanding was that both conditions had to be met in order to transition from closed loop fueling to open loop fueling? Not true?

I think my mistake may have been assuming that the pedal is @ 0% when at idle. We all know from the data logs that the pedal is @ 12% when its closed. IIRC table 1 for TPS enable conidtions is populated with 10's (10%) for the 500, 1000, and 1500 rows. 10 < 12

:hammer: I'm sorry Aaron I'll actually work on it here shortly lol. I'm wrong.

Eric,

I am looking at the last one I flashed and its in open loop? it will be in closed loop above 1000 rpm but for 500 and 1000 (hot idle) its open loop.

So whats the deal with the latenct being .032 m/sec? Is that a scaling error after you apply the patch? IT didnt seem to get clarified well enough for me.

Aaron

Bobby, I don't see why you couldn't use that patch on the SD rom, as it inherits the 9653 V7 base xml... here are the settings I used to get the car to idle in closed loop at 14.7 with my car on pump gas... it may vary a bit car to car, but I am sure you can figure it out... basically drop the minimum IPW until the STFT stops going haywire and the car still runs good...

does anyone have the patch for minimum IPW on ROM 96531706? I used the one provided by Fast Freddy that he gave to Babi (Crewdawg130), but it won't load. I'm still running stupid rich at idle because of it. Any help would be greatly appreciated.

I installed FIC 2150's and running e85 all the time, just FYI

yea, I tried it again and it still wouldn't install. Not sure what the problem is. And I know you said that it shouldn't matter if its specific to the ROM ID as long as its the 9653 base, but could it be an issue? Just curious since it doesn't seem to want to populate. Thanks Fast Freddie for the help.

q for you guys: what is the min ipw step that can be logged in evoscan for the evo 10? for the ap, its 0.256 ms.

whatever the formula dictates...

Eval = x/1000

so assuming x changes in 1 degree intervals, then 0.001ms would be the minimum step.

0.256 doesn't sound right??

Oh - do you mean the resolution of the IPW rather than the logger resolution?

This is the first problem, the standard ECU will only allow jumps of 0.256ms, so you can use 1.024ms or 1.28ms.
