You forgot to mention that you have to set the fixed angle back to -10 after you set the base timing, otherwise it will be "fixed" at +10, or whatever you set with the CAS.
What tuning software are you/he using? In tunerstudio you select "fixed timing" set what you want this to be. The default is 10 for miata base map. Once base timing is set, change "fixed timing" to "Use table" I don't have to change anything to -10.

If he set his base timing by adjusting his trigger angle, and then loaded someone elses map. He would have to adjust his trigger angle in the new map. If he tried to run it "as is" the timing would be off. Another point for: "Reasons not to blindly uploaded other peoples maps."

I'm wondering if this could be the culprit. Did he adjust the trigger angle in your map to match his setup?

Ah. Megatune uses a fixed timing value of -10 to "use map." So, with Megatune you set fixed timing to +10 and change trigger angle until you get to +10 on the dampener with your timing light, then change it back to -10 and MS will set spark angle according to your map.

I don't even know if he used my map at all. I just found it odd that the spark angle in the log didn't change at all. Maybe this dude should be left to his own destructive devices at this point?

Well, with our posts, i think we have done our part. We have explained how to set base timing then get back to reading the spark table in two different tuning softwares. If advance still does not occur, then I would start looking at bad CAS.

Cali cars have sequential fuel iirc. JDM is batch fire.

still doesn't solve why his timing output is stuck at -0.2

Is your req_fuel 5.8? I run 5.7 on 550cc! Your required fuel is too low. Try 7.1

Also don't use you AFR targets with the table set up like that. You're averaging 17-1 with your idle cells at 19.8-1. It will never run like that.

I think you need to work on your spark table too. 30 deg. advance at idle might be considered a bit aggressive.

Your cranking pulse widths are backwards, PW should increase as it gets colder.

Do you have a second map sensor fitted? MS thinks you do.

You need to go over all your tables and make sure they are appropriate for your setup!

Hello All im the guy trying to help out TTM i've been going crazy on his car I Know emanage ultimate, Chrome, neptune, Hondata and alittle about haltechs

So ive been trying to help get his car running

okay So Im trying to learn about the megasquirt with him

to get the Timing mark on the pully to line up the fixed timing need to be adjusted im looking at it now im thinking i should have played with the trim angle... but i think the car started to die when i touched that can't remember

even if the timing was locked at 10 degrees the car should at least idle nice? what would it have to do with the afr's?

touch the gas it dies in a heartbeat it has fuel cut

I changed the req fuel up to around 9-10 and it was able to idle but only at 200% ve....

I dont know if its been mention the car is a JDM RHD miata using a jumper harness between the megasquirt and ORIGINAL engine harness I'm wondering if there is something slightly different a wire grounded differently or a resistor somewhere in the harness

change your base timing at the CAS instead of doing it in the software.
aka when it reads 10 degrees in the software, your car is seeing 10 degrees.

having tuned all of the other systems you have, that should have always been the starting point you do on any ems.

You guys sound like you should give it to someone who knows something about the systems.

At -10 no matter how much we move the cas it will not come into the timing marks to get into the timing marks it had to be adjusted in the Megasquirt

TTM is trying to find a local guy that can come out and look at it, he is willing to pay, just doesn't want to pay a shop price

at -10 you dont have anything on the crank pully and from what i understand with your timing map at 30 degrees you wont read anything.

Set static timing to 10 degrees POSITIVE and try.

Ok, or pay someone... neither of you know.
Most reputable shops i have messaged stay away from MS since so much relies on setting it up properly from assembly to wiring etc.

The unit is fine. We cannot get the timing within the timing marks. Why do we need to get someone that knows about the system. Weve had 3 fluent megasquirters and have not been able to figure it out.

I wouldn't rule that out just yet. I'd try to find someone in your area that has a 1.6 with an MS and swap their known working unit into yours. I've seen harnesses have broken solders inside and also boards.

Have you double checked to make sure that the timing mark you are using is correct? i.e. it lines up to the TDC mark when you are at TDC. Alignment nub on crank pulley is at 12 oclock, cam sprocket marks are lined up.

The crank pulley on my engine that the precious owner put on has timing marks that are 180 off. (May not have been a miata pulley) I had to mark it manually.

I would double check crank pulley marks at TDC. You may have a situation like me where you have to mark TDC on your crank pulley manually.

Sooo imma gunna Kill TTM..... He told me the pump was wired okay he did some wiring jiggabo ****

I finally got my Voltmeter back and got to finally test it gets what? Fuel pump wasnt getting power it would get power when cranking so it would fire then voltage would completely drop off....

I ran a wire Directly from the battery to the pump and it ran perfect on a map that was given to him

the hesitation i could work on now since it was running, was the Accel enrich was on the map sensor, swapped it to the tps mint runs good now

ran out of day light and need to finish up the exhaust and bleed the rad better, and wire in a relay for the pump...

Ive got a spare rx7 FD knock sensor here will it thread into that hole under the intake manifold? (that is in the block)I wouldn't mind wiring that in to help further along tuning (anyone know the settings/freq for it)



Also Im very close to giving up My Turbo FC for a miata i just love how this thing looks lol
