If you go to advanced and then output test mode, you can set the spark outputs to fire. Does this fire both spark A and B?

I'm using Tunerstudio lite so not the full fat edition. I would imagine that's an error too lol

OK so I purchased a new BIP373 coil driver and soldered that into Q16 for Spark A and booyaa Job Done. All working fine.
Thanks for everyones help, I will now try an dget her idling smoothly and go from there. I have dampened the MAP signal so I can use Speed Density
Mapping. I hope this works.....lol

Congratulations, I just started up my zx9 engine today with megasquirt doing the ignition and using the carbs for fuel.
I too was getting your problem with when trying to rev the engine I was getting random 0 RPM instances, this was indeed the ECU looking sync because
of incorrect VR sensor wiring.
Is there any reason why you are using Speed density rather than Alpha-N?

I have done some reading in the subject and a lot of people say to use alphaN with ITBs due to the irratic MAP signal. However Speed Density is the
best way to tune. I have dampened my signal and tuned out the pulses from the ITBs so the variation in signal is no more than 3kpa or less. If I have
to change over to AlphaN I will use blended maps like some others have done.
Anyhow onto whats happening at the moment, I am at a stage where I am just tuning for idle as I have had a few issues no engine related which have
held me back. I am at a minimum idle kpa of 47 which is too high as far as I am aware. S I believe I need to richer the reqfuel up so I can lower the
ve as it is currently sitting at 55-60 at idle.
Congrats on getting yours going!!!!

MAP (speed density) in NOT the best way to tune ITBs, you will not have enough MAP resolution to get it tuned correctly.
Use alpha N or put and air box on it and use a MAF (which IS the best way to tune any engine ;-)

Guess I'm still on a huge learning curve lol.
Thanks for the heads up. I will get going on it ASAP.
With AplhaN, every time you balance the throttle bodies you have to recalibrate the ve table don't you? Is there a process to follow from the
get go or is it suck it and see, backwards and forwards until she runs ok and then set to and tune.

I'll be setting my zetec up on megasquirt in a few weeks (months), is there an idiots guide for a process to go through??

Go over to www.youtube.com/extraefi the guy over there is great at explaining things, he goes through every option that tuner studio offers, what they
do, and what values/settings should be in each option for various engine setups. He also goes through a series of videos that include the setting and
values for the first start of your engine etc. very useful information.
@GreenHornet - You should only have to balance your throttle bodies once...

The you tube vids are very informative and worth subscribing too.
Another argument is whats best, tuner studio or mega tune? Obviously this is for MS1 extra that I'm running. What's everyone's
preference?

I thought that Megatune has not become obsolete and now TunerStudio has become the standard for tuning Megasquirt ECU's. I'm pretty sure
that I read that there was no longer going to be updates for Megatune.
EDIT: On the DIYautotune website it says "Please note: MegaTune is obsolete and no longer supported. TunerStudio must be used for all
MS2/Extra revisions greater than 3.1.0 and all variants of MS3." which suggests that you need to use TunerStudio if you are running the extra
code

OK, so tonight I changed the settings from speed density to alphaN. I have recalibrated the tps and got a reading of 51 closed and 209 wot. So I have
adjusted the x axis numbers from 45 to 210 with a large ports of the axis devoted to less than 60% throttle opening as this is where most of the daily
driving and cruising will occur. Does this seem reasonable?
I have looked through a lot of the extra edi videos again, (I'm a subscriber to his channel) but I can't see anything on alphaN tuning. S
where do I start?
What VE numbers am I likely to see? What ideal VE numbers should I be aiming for?
One more final question, I have I putted my engines details for the reqfuel and get 16.6 in the top box. However it feels like she needs more fuel as
she dies when I touch the throttle any more than feathering. Unfortunately she smells rich so I can't understand what to do. Years of messing
with carbs and now I'm buggered with this modern trickery lol.
Any help always greatly appreciated.
