Ill have a stab in the dark and say its a Vipec :D

Of course it is. Dirt man would be all over his arse shitcanning any thing else. ;)

he would say he was only joking tho. ;)

Edited by FineLine
im going over to the dark side mate. I am pretty sure with this ECU i can add a MAF if the MAP sensor pisses me off (this is a very good quality ecu so apparently this will not happen)

As for how the IM240 machine works at the RTA, i have NO idea.

But i do know how the machine reads, what it reads for and whats acceptable levels for whatever car.. I also know what levels are high medium and low when doing the dummy IM240 tests on the dyno instead of the guesswork i have been using previously.

Should be tuning another car for emissions very soon.

Fair enough , maybe having enough processing power to run everything in real time rather than count back etc may make a worthwhile difference . If it can self learn maybe the MAP system can stay on top of things .

My aversion is because I don't think inlet manifolds that work as an inlet manifold are real good at giving pressure signal clarity to a pressure sensing devise . The fluctuations in common plenum manifolds often don't give much idea what the engine wants because reversions don't mean much to an EMS . IMO the conditions upstream of the throttlebody/s

are what needs to known and a MAP sensor can't do that for you .

That aside I would always insist on having a system that can do MAF and MAP , like you said it leaves your options open .

I would also insist on something that can read the std optical triggers and run the six coils and fully sequential injection system .

Best of luck , cheers A .

yeah for sure!

I got another 3 emissions test to do... still got some more projects on the cards

once you get the map system sorted are you going to go for another emissions test?

assuming the MAP system wont be effected by reversion?

Hey mate

I did this for you on my last tank of e85 before going back to 98 (just untill i learn this new ecu)

I got 320km's to a full tank, and i did boost it a few times, did not drive like a granny. I used to get 350 - 430km's to a tank with 98

Once the car was tuned properly the e85 consumption was much better from when i first started.

Few things i noticed after the switch back to 98.

I have stalled the engine 4 times:

the fuel gauge does not go down to a quarter of a tank after 50km's

i cannot go up hills in 3rd gear anymore

i am changing gears more often then before.

i lost 40kw at the wheels

I am going to the United servo in Newcastle tomorrow to try and convince them to stock e85.

great thread mate, and very interesting work. thanks for sharing it. there is one simple little comparison I'd love you to do if you can. next time you fill up on e85 fill the tank full and re-set your trip meter. then when you go back fill it full again, read off how many kms you travelled and you can do a quick ltrs/100km figure. then try the same with PULP (if you ever use it again). XXXkms to a tank is a big vague as you have no real way to tell how much fuel is left in the tank and I don't even know how many ltrs a GTST tank holds! I'd love to know the ltrs/100km figures and it would add one more usefull figure to your so far very thorough investigations. :rofl:

Good luck with the test this arvo.

you have inspired me GT...

i've been looking into this for a bit and think i will give it a shot when e85 gets popular and we get pumps around melbourne. (ie after the v8 supercars start using it next year)

i've found a tiny laptop that i can permanently install in the glovebox for $400 and now i just need datalogit :) (CBF lugging around a loose laptop)

just hope my injectors handle it... dont wanna have to upgrade them again :D

I have 740cc, at what power level would the injectors be maxing out running E85? 330rwkw?

i got 340rwkw with e85 and was only up to about 70% injectors. heaps of room for more (i have 740's)

injectors are 555's i currently have 265rwkw on 19 psi 2835 pro s

you should be right to reach 300rwkw with e85

ohhh well just tell him its ok because you dont have a horse power figure goal, you have a KW figure goal =)

sweet... i was thinking 300 would be the e85 goal ;)

*cue ash telling me not to have a horsepower goal figure* :down:

    • 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.
