After reading right through GT's and Joey's E85 threads i have become inspired to make something more adaptable to everyday streeters wanting to run this Flex Fuel stuff caltex is bringing out.

I'm getting quite keen on this caltex bringing Flex Fuel to the ACT :)

so much infact that I'm looking at doing a CarPc type thing so i can change fuel Maps from the sterio/GPS/Touchscreen...

Here is a one-click program i just wrote to change maps on the fly...

This program automatically opens up NIStune -> Opens the correct map in NIStune -> connects to the consult -> Updates the Map and Burns it to the ECU -> Then returns to the desktop... All in about 5 seconds :)

Obviously you need to have the maps pre-tuned for each blend

I think this is a pretty good option for us running NIStune to take the benifets of Pump Exx fuel...

for those that don't want to have a laptop in the car the whole time that is ;)

I also have plans to investigate the Ethanol sensors and make an auto adjusting map.

This won't be in real time (like the flex fuel cars) but after you fill up run the program and it'll get the Ethanol content and change the map to suit the current blend in the tank...

But one step at a time!

So if anyone can see any major flaws in my plan please speak up, as I'm keen to get something like this availiable for everyday streeters wanting to run Flex Fuel

I have that already with the dip switches on the unit but I can only switch in one fuel and one timing map. This car pc idea is a lot more practical than lugging a laptop around in the boot like most of us do.

Fair enough, Not sure how you would get around the panel that asks "do you want to communicate with the blah blah blah, prob just as easy to load the EMU software onto thew car pc and open it at the servo and load up the map you want and drive away.

this is a great idea, hopefully something can be made easily so that i could run e85 for track days etc and PULP 98 when just getting around town.

i've been wanting to run e85 but the worst part in SA is that its only available from one servo.

so if i wanted to take my car for a long drive away from the servo i would have to plan ahead and make sure i could get there and back on one tank.

it'd be handy if i could just switch to a different tune and run e85 only when i want to really make some great power

Good to see some interest in it :)

I'll be building my CarPc up over the next month or so and the fuel isn't avaliable untill somewhere near october, so untill then i won't be able to work out all the bugs and teething problems that'll come with it no doubt...

Also those people running a CarPc, whats it like with booting up times and stuff?

I'll be running mine as my sterio so i ain't gonna want to wait 5mins till it starts playing.

If anybody has gotten around this with another battery and a relay setup so that the computer never turns off let me know.

Also for the EMU stuff, if it runs off windows then it's possible to write a program to automatically connect and change maps.

That's all this program does... just takes out the human interaction and presses the correct buttons in nistune on its own... Basically...

So any automation in windows is possible, as long as the software to talk to the EMU is installed

Nothing special as far as windows install goes, haven't leaned the installation out at all.

Boots up in about 30 secs.

If you get a decent PSU and wire it up properly, the PC will commence booting as soon as the the key gets to the ACC position and won't reboot while cranking.

I also use mine for music but I cbf wiring the PC to an amp so just run RCA out from the front of my CarPC case to the Aux jack on my deck.

Update.

Got my CarPc up and running. with the nistune software on it.

I also now have a nice PULP98 map and an e70 map.

Over the next few weeks when I have time I'll be finishing off the programming and scripting to get the "one button fuel map change" going.

I will make up a "Mid Map" where i use mostly the PULP98 timing map, but adjust the fuel to suit a 50-50ish mix for those pesky occasions where you're at the coast with half a tank of fuel and not enough to get home and no one sells the good stuff...

Also looking at doing a one button "lean by 1 AFR" and "richen by 1 AFR"

Failing somehow integrating the ehtanol content sensor into NIStune, i reckon this'll be about the best way to make the most out of the e-flex and e85!

I'll get some pics up soon :blink:

Wait till you hear porn through the stereo.. strangely seems to have some serious bass to it :P

P.S. good work on the NIStune front, keen to see results :D

Love it, I've had my customers switch images via hardware but it relies on the driver to have some idea rather than be asked. NICE WORK!!

Has Matt added this code to his latest beta?

Nar mate. I'm working on this as a stand alone from NIStune.

Although i would like to work with matt, i love what he's doing with these NIStunes, this is more of a script than more software. The script/stand alone program will open up nistune and automatically use nistune's ability to change the maps in the car.

you have to have the maps ready avaliable on the pc and it'll just grab which ever one you ask it to and chuck it in the ecu, then quit and get back to your porn... lol

I'd like to see how the ethanol sensors will work with a ViPEC ECU...

Otherwise, good work Pat. Keep it up!

Fine, the link G4's have no issue so its carbon copy wont have an issue.

Not enough room on the nistune boards to run multiple maps, wish there was as we do a fair bit of nitrous and e85 (2-3 a week).

Matt and peter explained exactly why not a few years back but i forgot...

      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.
