So did the af ratios get richer when you had the e85 tune and filled up with 70 yeah?

Yes, about 1 afr but I only noticed it on the third tank as I never empty it fully. It made an extra 15 or so kw as the tuner took the fuel back out.

Excellent! So no pinging on the E70 with E85 tune?

I doubt e30 would ping, it just ran a bit rich. We took a bit of fuel out obviously and dumped a bit more timing in, mainly to make up for the stock ecu taking it away again.

Im not sure what this engine can take, no one has gone this far with the stock motor or even had one apart in Australia. VQ25det runs the same stroke as the VQ30det so hopefully they run the same rods as they are good for 400 odd apparently.

I have a spare VQ25det here to disassemble, and a VQ35de also, Im hoping I can frankenstein the two together to keep the awd on the 3.5, and run a GT35 or bigger if this engine ever lets go.

awesome! so there's no chance of any damage of ANY kind should the mix at the pump change. Just watch the AFR as you leave the station and drive down the road so you know if you should swap maps :P

Pretty much, theres not that much difference between e70 and 85 really, it may cause damage if driven hard on the track, it will probably run about 13:1 on e85 I guess if I drained the tank completely. Remember, all I have to do is wack a bit more 98 in anyway.

Best part is the starting has improved, I dont have to prime it with petrol anymore. Wish summer would get here...

I spoke to the manager at caltex nichols, they have had the engineers checking out what needs to be done to the lines to change them over to e85 a few weeks back. So it's very much gonna be in by the end of next month :P

One of my colleagues just told me that Caltex at Tempe in Sydney have it for sale now, it's priced at $1.09/L!!

Thieves, and yes it states between 70-85% ethanol on a pamphlet. We'll be keen to test some before next week if we can

I wonder how they price theirs? Isnt that the same price as unleaded?

I might have to quiz Caltex on their OPEC based pricing structure and get today tonight onto it. lol.

Unleaded was $1.20, certainly not a good way to get people to convert if they have to buy a fuel flex box and have poorer fuel consumption!

20c lower than unleaded seems to be their national pricing policy, im not complaining at the moment, 88.4c last fill.

I dont think they care about conversions, this is aimed squarely at the new E Flex range of vehicles as a global GM push. Notice they said its not suitable for any non flex fuel cars...

damn you, the next day after your visit i was filling jerry's with e70.... then slapped the race car on the dyno.... i said i wouldnt... your a bad influence :happy:

how'd you make more power on E70 scotty compared to E85?

hmm, i have our Rb26 700's on ebay atm cause they ran out on E70.. i raised rail pressure (alot.. alot) to get 380 @ 7000rpm and 17.6psi but ran out again of fuel well below peak rpm (backed out @ 6200) and power.

i just ordered id 1000's and if your out by 403kw im second guessing my choice

ive still got 6-odd psi and 2000rpm to go.....

just out of interest were you watching fuel pressure? its not a pump issue is it?

how'd you make more power on E70 scotty compared to E85?

It felt stronger than manildra even running rich, we took the extra fuel out and made an another 15 or 20, thats all I know. We were mainly tuning for the fuel and working on the ramp, I need more low end response.

The only other dyno I have used is RE's one, notorious for being 25 under. This one may be a little happy but Trent cant get it on his hub dyno to get an accurate graph. (he tried and couldnt get the front driveshafts out of the way enough to run it up.)

Sorry if I got you keen again Trent, you seemed to be over the tuning game, I just needed to light the fire again. Not bad fuel hey? :happy:

My workmate tuned an EVO on Caltex pump ethanol yesterday, didn't display any differences from Manildra, United or 'Super E85'

Of course there are differences, its e70 for a start which means less fuel required, (better economy) and no cold start issues. Is it a daily? Perhaps he doesn't drive it enough to see the differences? I bet the tuner did.

On the dyno, there were NO noticeable differences between tuning it on Manildra, United or E85 mixed with 98. We do about 5 E85 tunes a week and have so for about a year. I'm just relaying a message from the person who tunes them.

Edited by PJ.

You may not notice the differences unless you tuned for them back to back as I do. I have used all three and while you can drive on each with any e85 tune, the United runs leanest, then manildra and Caltex is rich. Each fuel feels different and smells different at the tailpipe. Perhaps im just becoming an alcoholic. :happy:

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
