Megasquirt Mayhem. Please Help.

[Chabs]

awesome, just downloaded the instruction manual. the owner before me didnt know anything about this stuff, and it says to calibrate every 10 000 miles or twice a year. it was DEFINITELY not done.

i'll let you know how it goes,

thanks a lot.

you also need to calibrate the sensor in megasquirt. It's under the Tools menu - Calibrate AFR curve. make sure your project is set to wideband and not narrowband..

[Chabs]

just did it, and now im getting readings in between 2 and 3. when i revved the engine it dropped to about 1.5 for a split second and the car almost died..

its running VERY rich, the exhaust smells like gas.


what... the fuck

[nando]

did you calibrate the Megasquirt curve yet?

[Chabs]

nope, we didnt...what will that change and how is it done?

Im not familiar enough with MS to know all these things haha. it was in my e30 when i bought it and im trying to get a hang of it.

[nando]

you using megatune or tuner studio?

in any case, it's under the Tools menu > Calibrate AFR curve. You probably want to set it to Innovate Default.

[Chabs]

using megatune. thanks for the help, gave up for today but will be back at it within a couple of days haha

[nando]

whatever you do, don't trust your AFR gauge until you're sure it reads the same in both logworks and megatune.

[Danny]

haven't connected it to the innovate.. how would i do that? is it possible that i need to replace the o2 sensor?

Really?

That's your issue right there.

I am actually having pretty much the same issue. I have an rs4pro3 plug and play (its not by the way) megasquirt setup. I have an Innovate LC-1 wideband configured to dual wideband outputs. I have one output connected to a gauge and one to the megasquirt.

My gauge reads 12-14 AFR's and in megatune it reads like 4 or 5. I don't have the calibrate AFR curve option under tools in my version of megatune.

Oh and I tested the outputs on my LC-1 and get exactly the same voltage on both of them.

[nando]

you need to calibrate the gauge in megasquirt. this is basic setup stuff, non-optional.

Seriously, have you guys read nothing on the subject?

[maniacmatt]

Thats the whole reason I bought a supposedly plug and play kit, I expected the basic set-up to be done.

I don't know where in megatune to adjust the settings with my version as it is not located under the tools menu.

[nando]

you can't expect it to be calibrated to your car though. you still have to do *some* work.

tools > calibrate AFR table. If it's not there try enabling advanced options. also you need to make sure your project is set to wideband.

[maniacmatt]

I am using megatune 2.25 and the MS1 Extra 029y4 project. I don't see anything like what you are describing for calibrating the o2 sensor.

I have Basic Settings>Exhaust Gas Settings. I have the EGO sensor type set to wideband and then there are things like EGO switch point, Ignition events per second and on and on.

I don't see anything else that could be used to calibrate for the o2 sensor.
