Thanks! I'm slowly learning some. :noob:

your priming pulse width looks odd, but then I dont have a turbo. It start ridiculously high, but that might be a error on my side.

Aha! I think I figured out why my laptop was randomly disconnecting from my ecu after some time!

Here's the culprit:

The fuel pump does prime for what seems like a longish time. But the car fires up right away for the most part.

I know it seems like you are talking to yourself but you seem to be doing a great job of learning on your own. I would suggest that you hand tune the top of your table to make it richer before you go out and use VEAL. You don't want it to run too lean while you are in boost until VEAL corrects it. It would be better to be a little rich and let VEAL lean it out.

I did this today and OMG the car feels greatish for now. Basically went out in the cornfields of IL and just sat at certain rpms and let VEAL do work on the high end.

I got lucky and my tuner is actually coming to visit me tomorrow so hopefully he'll be able to tap out even more awesomeness.

I kinda feel like my fuel table looks like dick-all but at least the car stays perfect around 11.5 afrs in every gear right up too 6500rpm. I'm running wastegate pressure so around 8psi. I creep a little bit after 5000rpms in 5th and 6th but my afrs still stay around 12.

It's so nice though! I feel like I have a new car! So much more drivable.

If anyone is interested in my progress, here's my latest msq. I'll see if I can get a new datalog up tomorrow.

Yeah this is always a good idea. If your fuel map is in the 90%s up top and VEAL is bringing you up to say 130%, go ahead and make everything up top 130% and tune from there. Better to be pig rich and have VEAL pull some fuel than the other way around. Then you can work on smoothing out the transitions.

Ok here's what my tuner and I were able to come up with today. Had a odd issue with my boost controller so we just tuned for 8psi.

Read below to learn why you didn't receive any more responses.

EDIT: Ok I adjusted things again now I'm idling perfect at 14.7. :D I also drove the car around town a bit not really going more then 4000rpm. Seems to be riding ok. I let VEAL do some tuning and things seem to be getting better. :D

Tomorrow I'm going to try and get out on the highway and let VEAL do some work in the higher rpms. Though I still need to figure out why my laptop randomly keep disconnecting from my ecu after 10 minutes. I'm figuring it's something to do with the laptop and it's power settings.

Good job figuring things out. If someone had held your hand you wouldn't have learned and retained as much knowledge. People helped where you needed it and things that could have hurt your car like letting it lean when tuning instead or enrichen while VEAL turning were pointed out.

what size injectors are you using?
any mod to the fuel pressure?
the 4.7 fuel required setting seems very low
have you adjusted for electronic latency?

FIC 650cc

That's how it came from Reverent. Haven't touched it.

Nope.

mx594m 07-03-2013 10:29 PM

just ran the calc for fuel required, and 4.7 about right for 1840cc/650cc/14.7afr
I am running 1890cc/525cc/14.0 and getting 6.3

latency, the delay in the system from the coil event to the actual spark is very car specific and is something that Dimitris cannot measure

measure/adjust using a timing light
1. check timing at idle, adjust to align crankshaft-pointer marks
2. have assistant rev engine to 4000 rpm, observe whether crankshaft-pointer marks are still aligned, adjust latency setting to align

I'm not sure what your getting at? your setup is obviously going to be different from mine. You said yourself 4.7 is right for my injector size and 1839cc.

mx594m 07-04-2013 07:25 AM

oophs, coils don't initiate the spark event, the CAS and/or cam/crank sensors initiate the spark event; but addressing latency is still relevant

at idle, any delay [and there will be delay] from the SENSOR event and the spark event will have little impact on power; different story at higher revs, delay [latency] means the spark event actually occurs after the optimal spark time with a corresponding adverse impact on engine performance

the megasquirt latency adjustment just adjusts timing for the delay

not saying you will add 20-hp, but you may add 1 more angel [on the head of the pin]

Ohh ok. Cool thanks for the input! I'll talk to my tuner about doing that.

Hey guys,

So I wired in the ebc I picked up from DIYAutotune and I'm wondering what parameters I need to set in TS to get it communicating with the ebc.

I did some searching and a lot of what i found concerning the ebc I think is outdated or another ms firmware.

Looks like this:

Mine looks like this:

https://www.miataturbo.net/attachmen...ine=1373240222


Can anyone point me in the right direction so I can figure it out? I'm just not sure what I need to set for boost control location and pin etc...

Thanks

Reverant 07-08-2013 02:56 AM

Everything is already setup for you - you don't have to change anything. Just start playing with the boost map.

Oh... ok then! lol :bowrofl:

Mazduh 07-13-2013 03:03 PM

Update:

I've got the ebc up and running thanks to rev pointing out a great 12v power source from the red/white wire in the MAF connector.

Playing around with the car at 10psi. Hopefully in the next few weeks I'll be able to make it over to my tuner's place so he ca dial in things for 12psi. I've got a few mechanical things I need to fix first and replace.

great work man, im about to begin my journey in tuning the ms, fingers crossed ive got a na6 turbo.
