Here is a print screen of the table you need to 0 out. I really dont know why they have this table on there. It makes for a very shitty unstable Idle. I find its much better to have it 0'd so the idle stays where the ignition map is and just set your ignition based on that.



I'll look at the ign vs. rpm table next chance I get to mess with it.

We have the tooth count set to two teeth per Ben's advice. That's what his is set to and his setup is running fine.

I do want to play around with another map I received and check the values.

When used properly, it makes all the difference between an Okay idle and a buttery smooth idle. I use it to great effect.

i am with ben on this one. that table and the fuel vs idle rpm and i can get my itbs to idle up when cold and come down nice when warm with no iacv.

Yeah i left the fuel correction the same but the idle was just really unstable with the idle air control valve and timing adjust together for some reason. Once I zerod it out, it was 10X better. Cold idle 1500 warm idle 1000 and pretty stable for the most part.

I could see how it would be a big help with no IACV. We will see as my new manifold does not have the IACV so Ill see how it goes to get a nice smooth idle

Okay so basically what I have done is this:

After comparing the default calibration to one that Blair had sent me a while back, I see that his settings are close in some areas, and far out in others, especially in starting/cold idle/etc.

I've taken a lot of what he's done, and copied it over to the calibration I will be working with. Obviously, we're using only a 1bar AEM MAP sensor, so I copied only the sections that matter with regards to this. Once I did that, I changed the injector size from 370's down to 330's so the fuel map changed based on this.

The ignition table was also copied, and I figured out where you configure the breakpoints at so that I could modify those as well. The calibration seems to make a lot more sense to me now, so here's to hoping we can at least get the car to start and hold an idle so that we can get the timing synced. After that, I may see if he wants to do some simple road tuning and then play with the VVL solenoid section (VTEC I assume is what he'll use for triggers).

Anxious to get the car back on the road, now!

cliff the configure out put section allows to dedicate a out put as vtec but all it really does is give you access to another fuel table. I am not using the table since I have my cams set to kick on at 5000 rpm no matter what. You can change them to cut on under certain conditions where the vtec fuel table would be handy.

Okay, so basically he has the VVL solenoids tied into inputs, and all we need to do is create a table or something that activates these inputs based on RPM, and that's it?

I think even without the table, you can set VVL to activate based on a combination of RPM, TPS, MAP, Vehicle Speed, and a few others. I recommend a combination of RPM and TPS control.

He wants to do RPM only, but I also think an RPM/TPS combination would be best. Say anything over 70% TPS and above RPM setpoint will activate cams. That way he gets the best of both worlds.

yeah its under configure out puts. then you can change a out put to come on under certain conditions(rpm,tps,load,ect). you do mean he has the solenoids connected to one of the configurable out puts right?
