Only thing on mine i can complain about is it pops and **** on decel even with over run fuel cut on and configured. It is working because I go full lean like it should and has auto tuned my fual map to 0 in the entire top row of cells. Still fuel getting in somehow to cause lame ricer popping.

Never had this issue with MS's overrun fuel cut.

Travis, would you mind sharing this map with me since I am in the exact same boat as Stein. Also curious about what you are doing in the software to correct it... trying to learn as I go!

God willing injectors will be here in a couple of hours and then tonight I will drive the car and be happy.

Cheers,

pops or burbles? you can pretty much zero out your 0kPa row safely.

Mine started doing this after the messed up dates showed up. It doesn't quite pop but it surges a bit and you can watch the AFR move around instead of staying full lean. Once I get the LC-1 in I'm going try going back to 1.0N and see if it goes away.

wow, finally... got a chance to log some time in the Miata today! Installed my injectors and resolved many of my little issues that were really bugging me.

Anyhow, I am using Travis's map with some alterations to make it work on my configuration... Things like VVT and the AEM UEGO which are not in his car.

For some reason there are a few problems really bugging me... on travis's map my idle is 1100-1500 RPM all the time; but worse yet is when I start the car it revs to 4k and takes a good 30 seconds to calm down to 2k or so. After it is calm, when I introduce a load from the power steering the RPMs go right up to 3500 or higher. Noticed that in my gauges window my ilde is 70? I have tried to adjust this out but do not have any luck in doing so.

Also have the sputtering under boost. Like Stein has said, I am gonna go out and adjust my asynch when the weather is cooler... it's hot as hell today.

Well, in any event, I am gonna post my map and see if there is something obvious that I am missing here... My eyes are tired and I am feeverish from a viral infection; so the brain is not working well and I really could use another pair of eyes to check me on these settings...

Oh, how can I tell if my VVT is set up right and could this be causing me problems when I use someone elses map that is known good?

Thanks all!
Cheers and off to take feever reducing drugs...

If I'm looking at the right file, a couple of things look suspect under the idle tab:

- open loop extra effort after cranking set to 20 seems high

-closed loop extra rpm for elec load set to 850rpm seems very high

- the overall control min. value is set 70, maybe reduce this - mine's set to 10.

If you haven't already done so you also need to set up the open loop base idle value.

before changing idle settings, verify your throttle body idle screw is set properly. if its different than his, it might make the difference.

also, the simplest way to rule out the VVT is to unplug the connector at the top front of the valve cover.

Would it be safe to say that if the car idled perfectly with the factory ECU that the screw is right?

Also, gonna pull the plug on the VVT now and see how it goes.

Thanks for the help and cheers!

maybe, maybe not. with the ISC valve closed, you want it to idle about 750.

I'm going to give this a crack for my 460cc Denso injectors (195500-2010):



Look reasonable?

Also, those with 1999 models, what dwell are you running on the standard ignition setup? Just the default of 2100?

Cheers

Not sure on dwell for injectors. Ignition dwell seems short though. I would try 3000us anyways.

This thread looks interesting:
'99/'00 coilpack measurements / dwell - MX-5 Miata Forum

Your figure of 3000 slots right in between 4 and 5 amps @ 14V, so it looks like it could be the go. I wonder if the thing would overheat if you aimed for 5 amps all the time (say 3400).

Nah, it should be fine at 3400.

Does anyone have a solid NB map no turbo on stock injectors running 101kpa maximum? I'm looking for a good solid map for the NB's to start people out on.

Thanks!
