haha that'd be great! Too bad you're not here in Melbourne. You could've come down and seen the setup first hand...But yeah, I might just take you up on that offer for the pistons and rods! I'll have a chat to Scotty and Cihan and PM you about them. Cheers mate  |

UPDATE:
Yesterday I purchased an E85 specific fuel pump (Walbro 400L pump). I managed to get the pump in and change the rubber hoses to E85 specific hoses with no trouble. We had to hook up the pump on a relay as we need it to run a constant 12V (stock pump drops to 8-9V on idle). All of that went smoothly enough...
I also purchased Bosche 1000cc injectors. Scotty was convinced we'd need them as the pump would instantly start flowing 4 times the amount of fuel to normal. With E85, we were instantly looking at a 15% power increase to petrol. On top of that, it meant I'd never need to upgrade them again if I wanted to push to 400+rwkw...
Later however Cihan came down for a quick road tune but he couldn't get the car started. We know the pump was working fine and after a fair bit of testing, Cihan concluded the injectors were the issue! The problem was that even though they weren't a complete overkill, the EManage Ultimate couldn't handle the right numbers to manage them (Or something like that - not my expertise ). We finished there for the day...
Today, Cihan came down again for another try but with no luck. The injectors were simply too big for the piggyback. So Scotty went down to the shop and bought Bosche 525cc injectors. We had them in pretty quick...Cihan tried again and the car started right away!
But now we had another issue 
Cihan noticed the EMU unit I bought off eBay from US seller bestparts4u turned out to be faulty. One of the injector channels wasn't working so we couldn't get all 8 cylinders going properly. Cihan tried all day different workarounds but no go He could get the car running smoothly on 6 cylinders or roughly on 8 with one of the workarounds. We were all pretty bumbed out 
Anyway, I've ordered a new unit from Greddy Australia. I'll try and sell the one I have now so if anyone is interested in an EMU let me know. Because the fourth channel on it is the faulty one, it will only be an issue with V8's. Cihan has assured me the unit will work on a 1JZ with no problem (as only three channels are required and the fourth faulty one wouldn't be used)...
And that's where we stand today. I'll keep the updates coming as we go |

Clayton, I won't be needing the rods as I've just decided to run the engine down (would be cheaper in the long run) but thanks for the offer mate!
Scott has also assured me the rods handle the power differently when the car's on ethanol. Something about the explosion in the pistons coming a bit later causing less pressure to the pistons/rods...Not sure if that was a good explanation but he seemed to know what he was talking about |

On another note, once I filled up with E85, my fuel gauge went haywire! It'd flash between empty and full and then stick to empty with the dash warning.
I looked this up and there seems to be a few threads were people have had this issue when they used E10. They weren't sure if it was the sender or the start to a blinky dash problem. This can put those arguments to rest. I have never had any problems with blinky dash (I assume this is because it's a later model) and nor have I had issues with my fuel gauge before. I believe the soarer sender simply doesn't agree with Ethanol fuel.
Does anyone have any ideas as to how to fix this? Cutting the dash warnings all together is not an option. One of the reasons for setting up the kit in this way was so we didn't have to get rid of the AFM (and have TRC problems) or any other functionalities that came with the car. I happen to like my little "scan" button on the dash
I can try taking out the sender and cleaning it but I don't know if it'll do anything. Maybe there's a replacement sender out there that might be ethanol friendly? Anyone..? |

Is it true the pov pack TTs had a float instead of the more advanced unit In the v8s?
Could this explain why some people haven't had issues with fuel gauges when using E10...?
Would they be interchangeable? |

not interchangeable to the best of my knowledge, how long has your car been sitting without being run Hays, could be just a simple case of the sender being all gummed up from the crappy fuel that they sell, not a very good shelf life. |

Paul, the gauge worked fine for the couple of weeks we had it running before converting to E85 so I don't think it's the senders. If the float sender is not interchangeable by plug, do you know if it would work if just wired in instead? |

Hays it will be the sensor, the tube sensor works on the resistance of the fuel ,and for some reason E85 is different , once you go back to petrol just clean tubes and all should be fine |

Thanks Dave but I don't plan on going back on petrol
This setup requires E85 and if you read the earlier posts you'll see we've put in an e85 specific fuel pump and upgraded the lines and injectors just for it. So we're looking for a fix for the e85 fuel sensor (besides going back to petrol) which is why I'm asking if a float could be wired in...thanks for the info though! |

my 96 has the tube type and once when running very low on fuel, pulled into one of those very cheap looking servos with a line of cabs being serviced or filled. Gauge did not work for that tank, (showed empty) then filled with BP 98 and all back to normal ever since... |

I had the exact same issue !
Topped up with 20l of e85 , and the sender went from empty to full and everything in between .
I replaced sender , same result .
Emptied tank , filled with 98 . Presto ! All fixed .
I wonder if you can use the float style with a pov pack ? |

I think you will find it has something to do with the way the electronics in the dash work for the different type of senders. It could be the E85 has a different resistance and could be that a simple clean of the of the sender may or may not fix it, couldn't hurt to try. |

Good point. Ill give the sender a clean and see if it starts working with E85 though I'm not expecting it to...which is why I've put up a thread in the wanted to buy section for a float type sender...maybe It can be wired in instead of the tubes :S |

What may be possible is to fit a float type sensor with a variable resistor pot on the return feed and trim it to match your V8 dash? |

Its not that hard hays, when you turn the volume control on your radio its a resistor pot , so you can adjust it to the right level, |

Yes, it is. That's why I want to swap it for a float type |

Interesting setup. You will find that the stock exhaust manifolds are terrible and will give you a top end restriction over 180rwkw, at least in a supercharged application. More peak power can be made, but there are diminishing returns using stock manifolds.
Reason being, the EGTs are too high for heavy use on a track or similar. Even when tuning they would glow very hot and detonation from the EGT temp being too high was evident through the knock sensors I use.
What you may find is an aggressive reduction in ignition timing, but the EMU can only take out -20 per map, so -40 total. I've never seen it actually translate to an actual -20 or -40 reduction, it's more of a correction factor than anything else, much like the INJ correction.
Having said that, it would be interesting to see how it performs with these mods. |

I never removed the stockies in the first place :S
Besides with this kind of setup, swapping them over is an easy job and doesn't require much modification to the kit so I can always upgrade in the future |

Update: After a week of back and forth questions, the ebay seller has refused to refund or replace the faulty EMU 
So to all out there, beware of seller "bestparts4u"
oh well...you live and you learn |

get yourself a real ecu anyway, even a old wolf v4 / v400 would do the trick and I have a base map you can have or if your budget extends to it the plugin v550 would be nice |

Ah. Just a tad late Allan but I appreciate it
UPDATE: I bought a new emanage ultimate straight from greddy Australia this time and we got it plugged in only this morning. The car is running smoothly again on all 8 cylinders and the afm can stay in its place (no annoying dash bong - except for the annoying fuel sender error).
We're hoping we can have it on the dyno early next week so hopefully the results aren't too far off now |

Hey guys,
I'm pleased to announce that the first set of results are in 
Okay, so after a full day of tuning, we had to only tune it on 2.5 psi max as the car is misfiring at anymore than that. I have to sort that out before we push for any more...
Note: I don't quite understand it (Cihan does) but there's something happening where the spring pressure put in to the wastegate is not actually the same pressure at the engine side because of the intake distance from boot to front. This is not an issue, just means I'm getting less boost than the spring is supposed to give.
So we started with a 4psi spring (actually getting 0.5psi) and we achieved 175rwkw! I gotta say, I was taken by surprise as I wasn't expecting that kind of number so soon!
The car is now tuned on the 5.4psi spring (actually about 2.5psi and it's hitting 181rwkw).
More results to follow once I get the misfire sorted 
(Sorry about the bad quality photos - took them with my iFail)

What are you aiming for? 250rwkw? Would like to know what its like to drive. Laggy? What revs does the turbo kick in? |

Scott, the turbo is kicking in by about 2800.
The next tune will be for 250rwkw. I'll drive around for a couple of months see how it feels, after that I'll go for 300rwkw but I think I'll need a shift kit for anything over 250... |
