GDay,

Ive got an Autronic SM4 on my R32 and was a bit dissappointed to discover that the lead that you plug into the serial port of your lap top is one of the older 9 pin plugs and isnt compatable with my new lap top. I was just wondering if any of the Autronic guru's out ther have come up with a solution for this, as ive heard that Autronic havent updated to a newer serial port plug. Is this true?

Ive also heard that the '9 pin serial port to USB adapter' that you can buy from Dick Smith etc ($80!!) is notoriously unreliable and doesnt work with all computers.

Can you get the lead modified at all, or is it not that simple?

Anyway, any help would be appreciated, as i really want to use my V DASH software and the data logging stuff on my new lap top. The car is getting tuned next week after being off the road for two years!

Thanks,

Shaun.

hey mate im not sure with my ecu but i guess id be in the same situation as u r with my sm4, i was supposed to get it back last night but i need another fuel pump, but when i go down there again ill ask and see what lincoln says

good computer choice!

you can get a belikn usb to serial adapter that works fine. my mate uses it on his sprinter.

Any USB to Serial adapter will work - don't believe what you are hearing. Any Windows XP laptop will work with this combination.

I used one for 3 years without a hassle - with the older clunkier SMC 1.99 software.

They will cost you b/w $60-$80 though. Chicken feed against the price of a SM4.

Great choice of ECU by the way. >_<

Andrew

Thanks for the info guys! As you all say, its an awesome computer; im really happy with it. Ill get the adapter then. I was just trying to save some coin thats all.

Ill also keep you all posted on the results of the tune.

Thanks,

Shaun.

We've found that the ATEN usb to serial to be the best runs everything we've tryed including autronic and datalogit.

Thanks for the info, but where would i get the 'Belikn' or 'aten' adapters? Just Dick Smith or any main stream electrical store like that, or are they more specialised than that?

Cheers,

Shaun.

Just for more clarification, my tuner uses the ATEN adaptor when tuning my Autronic so I would go with that.

Note I have an earlier version and not the SM4.

The Autronic forums will also have the info you need. A gold mine of general Autronic info there as well. Highly recommended.

Exactly what rob82 says.

Go with the Aten USB to Serial. This item will work.

Yep, for those wondering the same thing, the Belkin adapter works too! I just had to change to com port 8 under settings so the V DASH program would recognise the USB connection.

I love Autronics!!

Sorry, I don't want to high jack the tread but I'm dying to ask!

Wanted to know what everyone's fuel comsumption in from an RB26 with Autronics.

My fuel consumption at this point around 16L/100km's with some city and highway driving, so around 340km per tank.

I'm running an SMC 1.92 with 500R CDI

Im using 800cc injectors with 260in 260ex cams, this is stated as injectors and cam duraction plays a part in fuel economy.

Im not sure what my fuel comsumption is like yet; i just trailered the car to the tuners today. It'll be interesting to find out though. Can you run closed loop on the SMC? I bought the wide band oxy sensor so i can run closed loop on the SM4. Ive got 700cc injectors and standard cams at the moment.

Just a side note; the tuner just rang me up and told me that my Iraway 7 spark plugs ($180) were fowled beyond repair. I did fowl the plugs on start up the other night, but i removed them and burnt off the carbon etc with a gas torch. It then started perfectly. Is it possible to ruin plugs by fowling them with over rich mixtures? I understand that the car may not start, but would the plugs be stuffed beyond repair? Ive only started the car about 10 times on those plugs!

Thanks,

Shaun.

Yes, you can run closed loop on the SMC 1.92. The wide band o2 sensor you got, is it the Bosch item LSM-11? The SM4 will not accept a direct 5-wire wide band sensor, I have confirmed this with Autronics on their forum. It will do a 0-5V o2 sensor with voltage scaling for the A/F readouts. Still a better way then a narrow band 0-1V method

The SM4 has a very flexiable close loop control so will work very well.

What I would do about the plugs is let the tuner replace them but tell them you want them back. Give them a clean the way do did it before (best way I beleive) and stick them straight back in. I don't beileve that they are fouled beyond repair and even if they are, surely not all and even if they all are, well at least you have them back.

Let me know how your fuel consumption goes as I am interested in the results.

Good Luck with the tuning! Post the results :D

Yeah, ill post the results for sure! Im hoping for around 350rwkw, but having said that i dont care that much about a power figure; just as long as its nice to drive and usable on the road.

Im not sure what sensor ive got. I think its a Bosch one, so i hope it works the way i want it to. Ive spoken to the tuner at length about running closed loop, and i bought it off him, so im assuming its suitable.

Ill definately be getting the plugs back too!

Shaun.

I have to agree, always tune for best drivablity and what ever WOT figure you get, thats fine as long as its useable.

Looks like you got the O2 Sensor Autronics recommend. The LSM-11 is a 4-wire wide band as they call it which can be used as a narrow band sensor or a wide band sensor. It will only work wide band connected to an Autronics A/F Meter and when connected to a SM4 which will feed it the 5V and the tuner will use voltage scaling to make it work with close loop control.

I have used both closed loop control and just the target A/F in the map. You would be suprisd at how good the targets are when they are tuned at the correct A/F.

Only problem I have had is that the sensor would only read accurately to 15.5 A/F but could run leaner at certain load points when on cruise. If I disable closed loop and just dial it in at the rpm and load point the A/F I wish to run I could run leaner then when closed loop is enabled.

I not suggesting anything here, just the Autronics is so very accurate and precise - what an awsome ECU.

Is the tuner an Autronics dealer?

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
