New engine and air fuel ratio gauge

1
I've been able to do a bit of internet research on my AFR gauge & what it can do for the MV engine. Turns out you can customise the output signal or voltage, it sends to the ECU when you use it's 02 sensor in place of the stock 02 sensor. This is done by running the supplied program, plugging the gauge into a laptop & altering the numbers.(should read ALL the instructions before fitting & not just the quick install) Almost brings Digifant into this century. I'll have a go at it on the weekend & report the results. Hopefully I don't stuff it up! Eddie.
2
For all who are interested (in particular Greg E) I have just succesfully wired my AFR gauge's 02 sensor to run my engine at 2 pre determined AFR's.One at 14.7 for cruising and one at 13.5 for when the engine is under load. Works really well in prelim testing, has quite a bit more go when accelerating. Will see how it goes in normal driving during the week. Eddie.

Very interested Eddie! Do you have to have a lap top running in the car to supply the map? I have been looking at the gauge you bought and also db series gauge innovate also make and am have trouble working out whether the db can do what you are doing. The way I see it all I should need is a little more fuel pressure(2.1L to 2.4L) and acceleration enrichment (none on digifant). Thanks for doing all the hard work! Greg E

Yes Greg , running a lap top to adjust the values for each of the two analog out wires from the gauge. Just had a bit of trouble connecting the supplied cable to the computer (older type serial port connection rather than usb was supplied)Got the idea from one of Chris Corkins posts on the samba under "how to hack the digifant ecu". He runs a vaccum switch & relay to alternate between the 2 circuts. I'm not quite up to working that one out just yet! I think there is way more adjustability in this system and Ive just started . I'm sure you will work it out better than me . Eddie.

Just something to add to my last post, the gauge you're looking at seems to have just one analog out wire where as mine has two. You need the LM part of the kit to be able to adjust the values of that signal. I'm not sure if you can adjust it to run lean and rich from the one circut or if you need the two analog out circuts like my gauge has. I havent tried this as yet as the voltage increments the digifant reads are so small (.1 to 1.1 volts) I was pretty happy with what I had achieved(with the 2 circuts) for this weekend, so I called it good for now. Come to think of it ,if the db gauge has only one analog out wire and you need 2 different values you could alternate between the gauge's signal & the stock 02's signal. Easy!

Hi Eddie & Greg,
I have been following this thread with great interest. You both have
seen my after-market ECU setup at the day of the VW.
Unfortunately it did not work out. After all this time, I'm back to
factory plus LPG setup.
With my 2.4L engine, I'm also concerned about the air /fuel ratio as
it may run too lean.
So I intend to purchase the MTX-L gauge, Eddie, I would not mind
having a look at your set up.
Cheers,
Theo

Theo, sorry to here all that effort didn't bring the results you hoped for. A stand alone aftermarket system would give the best results but is very hard to get set up right. Gowesty were even saying that they were developing a plug and play piggy back module which seems to have gone by the way side.
Eddie, you are right about the DB's LC-1 module. It does have two analog outputs but once you use one for a gauge your down to one. Chris Corkins is using the LC-1 with no gauge (thanks for the forum link). So he uses the two out puts via a relay and vacuum switch. What I don't understand is how you are switching between your two outputs? Is it just in response to the o2 sensors output? If so would that not delay the response some what? If you wanted you could do what Chris has done, finding the vacuum switch is the hard part. No need to have lap top in the car this way.
I bought the mtx last night on fleay bay, here. On special Theo. Greg E

Greg, I'm switching between the two outputs via a dash mounted switch for now. One circut replaces the standard signal from the oem 02 sensor and the second I programed so it keeps the mixture at approx 13.5. I haven't played enough with it to work out if I can program both lean & rich from the one circut.
Theo just let me know if you want me to drop in one night on my way home or alternately I should be free Saturday afternoon if you fancy a drive to Mount Macedon. Eddie.

Eddie, If I can find a single pole double throw adjustable vacuum relay (approx 3"hg) it will be a simple addition to automate what you are doing with a dash switch. It may end up needing to be a vacuum switch and electrical relay if  I can't find what I want. If any members are into pneumatics and know where to buy such a thing please let me know. Greg E
P.s. I was up your way today. The inlaws have moved to Kyneton. Man it was cold. I bet you've got the fire stoked at your place.

Yeah it's cold up here Greg, fire's been on 24/7 since the start of May. The vaccum switch is what I wanted to do but after doing the rounds of the auto stores and local auto electicians I realised that my search for parts would be a bit more difficult. The closest Ive come to finding one was on a US site selling parts for classic cars( can't remember the site) Probably want an adjustable one so you can alter the settings as you please. Is what Phil's suggesting doable? Just a word of caution when you hook up your gauge, be careful to adjust the voltage out settings on the second circut. It has default voltage of .1-5 volts from memory which is 4 volts more than the oem sensor puts out. Could this potentially damage the ECU?. I didn't want to risk it so I reduced the max voltage to about 1.2 before I hooked it up & then played with the settings between 0 to 1.2 volts to get my 13.5 AFR. Eddie.

Thanks Phill, I probably didn't explain myself very well,this is the kind of thing I mean. http://www.omega.com/pptst/PSW-621.html
We need for a change in inlet vacuum to trigger a  switch between two wires and a common. Either that or a simple two wire vacuum triggered switch.
Eddie, Yeah you did the right thing. More modern systems use a five volt scale. All they do is set up two channels to suit the most commonly used systems. As you can see from the link above I have found a switch that would work, so they do exist. The hard part is they are all made for industry which makes them expensive and hard to buy in small numbers. I'll keep punchin'. Greg E

Yeah it's cold up here Greg, fire's been on 24/7 since the start of May.

Yeh i suppose I could do that. Fit it into an elecrtronics box and wire up a spdt switch. It would be a little bulky though. Thanks Phill.

We need for a change in inlet vacuum to trigger a  switch between two wires and a common. Either that or a simple two wire vacuum triggered switch.
Eddie, Yeah you did the right thing. More modern systems use a five volt scale. All they do is set up two channels to suit the most commonly used systems. As you can see from the link above I have found a switch that would work, so they do exist. The hard part is they are all made for industry which makes them expensive and hard to buy in small numbers. I'll keep punchin'. Greg E

Yeah it's cold up here Greg, fire's been on 24/7 since the start of May. The vaccum switch is what I wanted to do but after doing the rounds of the auto stores and local auto electicians I realised that my search for parts would be a bit more difficult. The closest Ive come to finding one was on a US site selling parts for classic cars( can't remember the site) Probably want an adjustable one so you can alter the settings as you please. Is what Phil's suggesting doable? Just a word of caution when you hook up your gauge, be careful to adjust the voltage out settings on the second circut. It has default voltage of .1-5 volts from memory which is 4 volts more than the oem sensor puts out. Could this potentially damage the ECU?. I didn't want to risk it so I reduced the max voltage to about 1.2 before I hooked it up & then played with the settings between 0 to 1.2 volts to get my 13.5 AFR. Eddie.

Thanks Phill, I probably didn't explain myself very well,this is the kind of thing I mean. http://www.omega.com/pptst/PSW-621.html
We need for a change in inlet vacuum to trigger a  switch between two wires and a common. Either that or a simple two wire vacuum triggered switch.
Eddie, Yeah you did the right thing. More modern systems use a five volt scale. All they do is set up two channels to suit the most commonly used systems. As you can see from the link above I have found a switch that would work, so they do exist. The hard part is they are all made for industry which makes them expensive and hard to buy in small numbers. I'll keep punchin'. Greg E

Yeah it's cold up here Greg, fire's been on 24/7 since the start of May. The vaccum switch is what I wanted to do but after doing the rounds of the auto stores and local auto electicians I realised that my search for parts would be a bit more difficult. The closest Ive come to finding one was on a US site selling parts for classic cars( can't remember the site) Probably want an adjustable one so you can alter the settings as you please. Is what Phil's suggesting doable? Just a word of caution when you hook up your gauge, be careful to adjust the voltage out settings on the second circut. It has default voltage of .1-5 volts from memory which is 4 volts more than the oem sensor puts out. Could this potentially damage the ECU?. I didn't want to risk it so I reduced the max voltage to about 1.2 before I hooked it up & then played with the settings between 0 to 1.2 volts to get my 13.5 AFR. Eddie.

Chris Corkins is using the LC-1 with no gauge (thanks for the forum link). So he uses the two out puts via a relay and vacuum switch. What I don't understand is how you are switching between your two outputs? Is it just in response to the o2 sensors output? If so would that not delay the response some what? If you wanted you could do what Chris has done, finding the vacuum switch is the hard part. No need to have lap top in the car this way.

Oh right sorry Alf I misunderstood. The jaycar module does not come with a wide band sensor nor a gauge and is not of the quality of the innovate kit. The Innovate kit also allows for modular additions latter. At $175 compared to $80 for the Jaycar I think it is well worth it. Greg E

I'm happy to report that all is well with my new set up . My syncro feels more like my 2wd to drive . Has power to accelerate , climb hills & even enough for the odd overtaking manouvre. I haven't really done an economy run yet as I'm constantly putting the foot down to check if that go is really there. The only drawback so far is that it gets the odd hiccup while driving before it reaches operating temp, but after it does, all is good. I haven't done much searching for a vaccum spdt switch as I only run on petrol when I need power so I switch to the richer mixture when on petrol. the rest of the time I'm on gas & the gas system I have runs off vaccum to determine air fuel mixture ,so the 02 signal is irrelevant. I'm contemplating setting up the same gauge/system in my stock 2wd to see if it makes a difference. Still have some fine tuning to do but has already exceeded my power expectations with this engine. Eddie.

Works really well in prelim testing, has quite a bit more go when accelerating. Will see how it goes in normal driving during the week. Eddie.

Turns out you can customise the output signal or voltage, it sends to the ECU when you use it's 02 sensor in place of the stock 02 sensor. This is done by running the supplied program, plugging the gauge into a laptop & altering the numbers.(should read ALL the instructions before fitting & not just the quick install) Almost brings Digifant into this century. I'll have a go at it on the weekend & report the results. Hopefully I don't stuff it up! Eddie.

Hi Eddie,
I'm just in the process of fitting my AFR gauge. Am I right in understanding that you are not using the factory O2 sensor but
instead the AFR sensor? Thereby be able to change the ECU setting with the lap-top?
Cheers,
Theo
