Re: DIY autotune

short answer is yes - there have been a bunch of people that have built/bought megasquirt setups especially with the creation of the PNP kits. What version are you looking into? If the S14 has a power transducer for the coil, then any of the PNP setups on microsquirt will run it. A lot of the talk a...

Re: I need some HELP!

Going by memory... Should be pin 1 on the sohc ECU. It's one of the three wires that goes to the power transducer.
And I've never wired in emanage so grain of salt warning applies.

Re: Ka24et timing map

no MAT (intake air temp) reading - stays at 70 full time. This needs to be fixed or your fueling during different temperatures will not be correct. Battery voltage very low through log - 11.3-11.8 at it's highest. Does the readout from tunerstudio match what you measure at the battery? Rich - mid 10...

Re: Ka24de Load Scale Calculation

Not a lot of experience tuning maf setups, but how I slowed my engine down and focused on certain loads/engine speeds is by left foot brake boosting. Easy to hold steady speed and high load for a enough seconds to find yourself in the log and note the tp load at that point. For a maf setup, I would ...

Re: Ka24et timing map

Is your idle pretty lopey? 10% fuel difference between load/rpm cells at idle is a pretty stark difference, and any change in rpm/load may send your engine into a vastly different fuel region. Same comment about your ignition table applies to your fuel map - load axis ends at 204kpa. I would prefer ...

Re: Ka24et timing map

First, comparing DOHC to SOHC timing maps isn't necessarily apples to apples - SOHC combustion chambers by design will require more ignition advance than DOHCs to achieve the same flame propagation completion relative to crank movement. Second, the way your tuner has established your load axis, mean...

Re: MSPNP2 Throttle position sensor issue

I have previously had some issues with the tps sensor reading when I hadn't tightened the ecu connector down tight enough. You can look at a dohc fsm to find the right tps signal pin, and measure the corresponding pin on the mspnp mainboard. See if you're getting some voltage at closed throttle (hop...

Re: Adam's formerly supercharged... now soon-to-be-turbo'd,

I'm no expert in nistune, but a couple of notes on that log in case it means something. At 11.8, that is where you observed the lean AFR. You don't let off the throttle until 12.4, where TPS transitions from 4.2 to .56. At 11.8, tp does drop, but isn't met with a corresponding decrease in mafs readi...

Re: Help with injector timing table

Looks reasonable. It makes more sense to me to speak in terms of btdc, so my table would be 720 degrees added across the board (to result in positive numbers throughout the table). I would probably give a little more time at 600 rpm (-340). And the other rule of thumb I've heard is to add 10deg per ...

What is your timing point (start, middle, end of pulse) set to?

Re: Help with injector timing table

General consensus is that all fuel should be injected before the intake valve opens. Unless there's a map missing from your view, aem treats this as a 2d table (rpm vs injection timing) vs megasquirt treating this as a 3d table (map vs rpm vs injector timing). Generally speaking, as rpm increases, t...

Re: seth's zenki build

I found the same thing. What it boils down to is cranking speed consistency - if the missing tooth aligns with a place where the crank is changing speed, then it is difficult for the MS to identify which tooth is actually missing. The best tooth#1 angles seem to be in the middle of the piston travel...

Re: Can anyone familiar with KA24E and MS3/MS3x look this ov

You're not trying to feed power to pin 4 by way of pin 36 - you are using pin 36 to activate a relay (which happens when current passes through the relay coil on terminals 85, 86) to provide SIGNAL from pin 30 to pin 87. In many cases, when a relay is used, you are correct in that the end goal is to...

that won't be a problem - the 87a terminal means that terminal 30 is connected when the relay is not activated, where 87 waits until the relay is active before receiving terminal 30's source http://www.rattlebars.com/avalanche/relay_basics.html For your question on table switching - it is necessary ...

Yeah, I think you're good to go now with the extra relay and getting the 12-1 disk (fwiw, you can run on the stock disk in basic trigger mode, and I did for at least a year, but I would recommend getting the disk now and not having to do it later. Gives you much more crank speed/position resolution ...
