Re: KA-T MS3X 17+ AFR Issue
https://www.msextra.com/manuals/ms3manuals/ My injectors are indeed wired for full sequential and all share the same 12v power source. I wanted to double check because I had not looked at the batch fire configuration's wiring. I did not know whether it shared the wires, only using inj wires A and B...

My injectors are wired as follows: Cyl/Inj 1- Injector A Cyl/Inj2- Injector D Cyl/Inj3 - Injector B Cyl/Inj4 - Injector C All of them share the same power source All of the ECU ground signal wires are going to the MS3X Edit: That last statement, I am not entirely sure about. I will try the batch fir...

Re: KA-T MS3X 17+ AFR Issue
If you've adjusted the position of the distributor AFTER verifying your timing with a timing light, it is no longer correct. Start back over and fix that first. I can't tell if you just changed it in tunerstudio or moved the distributor since you talked about that in your first post. DO NOT MOVE TH...

Re: KA-T MS3X 17+ AFR Issue
What is your base fuel pressure set to? I assume you're referring to the VE table as the fuel table. That is EXACTLY what you need to be changing at idle, NOT deadtime. Get your deadtime and fueling requirements set based on parameters, then change your VE table in your idle cells to richen up your...

Re: Megasquirt MS3X KA24DE wont start
Where did you get the 910cc injectors? Company/brand. Maybe we can help with your dead time and offset curve. They are actually Siemens Deka IV 875CC injectors. This and other updated information is in a new thread I created because my issue is now different than what it was when I started this one...

Re: Megasquirt MS3X KA24DE wont start
So, you got it running now? I finally got the thing to run but I am having issues setting up my injectors correctly as well as finding a very large vacuum leak. My throttle body shaft seals were bad so I fixed that. I need to do another smoke test. I starts and idles at about 1500 rpm at 17+ AFR. I...

Re: Megasquirt MS3X KA24DE wont start
I did remove the quadspark. I wired coils directly into the ms3x. I have the documentation downloaded if you are unable to find it online.mfschoenberg6522 wrote: ↑Tue Oct 20, 2020 8:11 am I assume you removed the DIY Quadspark, when you went with '01 Maxima "smart" coils?
Looking to go COP on an S14 KA24DE as well.

Re: Megasquirt MS3X KA24DE wont start
I got some 01 maxima coils now and I wired them up. That fixes my spark issue and I now have my base timing correctly. The current issue right now is that I am getting extremely high fuel pressure. 65-70 psi when I want it to be 43. I have a direct mount fuel pressure regulator and when I adjust it,...

Re: Megasquirt MS3X KA24DE wont start
I have tried cop and wasted cop. Going high and going low. The coil is still getting hot. I went back to the settings that I had when they were fine and they are still getting hot. I have changed none of the wiring. It could be possible that when the coil overheated, the components in the plug were ...

Re: Megasquirt MS3X KA24DE wont start
Can't find the manual for the 30-2850, they were superceded by 2854 which are >Here< https://i.ibb.co/VJB7zR2/coil.png So the setting in MS is uncorrected before voltage adjustment, I'd set it for the 14v value of 2.4ms As far as spark duration goes, 5.0 seems a bit high. I'd lower it to 2.0 and go...

Re: Megasquirt MS3X KA24DE wont start
Nope, distributor phasing doesn't matter one bit if he's not using it to fire the plugs. Only thing in the distributor he is using is the trigger wheel. All he needs to do is find tooth #1 angle, then Megasquirt takes care of sending spark to the correct cylinder. If he ever removes the distributor...

Re: Megasquirt MS3X KA24DE wont start
1.5.1 is correct version for MS3X. Your Basic/Load Settings look okay. But in General Setting you may want to change Incorporate AFR Target from 'don't include' to 'include'. This will make your VE table more meaningful. In Ignition Settings tab under Ignition Options/Wheel Decoder I see one error....

Good advice from D21turbo and I'll echo that, plus this; http://www.megasquirtpnp.com/docs/mspnp_g2_ns9501_s14.php?isModel=1 That article is for the MS2 but everything about Verifying and adjusting base timing...

Megasquirt MS3X KA24DE wont start
I would appreciate a bit of help here. I have bought someone else's project s14 with of course a KA24DE. They installed an ms3x and some performance mods to set it up for boost, but lost interest when they couldn't figure out how to tune it. Tunerstudio does not seem to be the most userfriendly. I h...
