  1. Another one? What would the injector flow rate be at 43.5 psi for ID 1050x. There is g4 characterization data on the ID website but no specific to ethanol
  2. Thanks Adam. I'm working away so can't respond to this as often as I'd like. Does the Density Temp Coefiicient make a big difference? Can you show me the equation to do the calculations
  3. Bugger. I was hoping that would not be the case. I couldn't work out how to do the calculations. My BP 98 petrol here is 14.4 stoich. I have been trying to google the information to no avail.
  4. I'm looking to run E30-E40. I don't have enough injector or pump to go full E85, so I won't be tuning the second fuel at full strength for the tables to extrapolate between in the blend table. The Link help files give all of the fuel density, stoich ratios, etc for E85. So lets say E30 is going to be my second fuel would I tune the car on E30 and set up the Multi Fuel Blend Ratio Table so that everything over E30 is at 100% and leave the known ethanol properties in the multi fuel table.
  5. Simon, seriously mate, take the Horsepower Acadamy courses. You already seem to have a fair idea what you are looking at. HPA will simplify the whole process for you, break it down into a couple of main areas and give you the skills and confidence to slowly sort out this nightmare properly yourself. Not only will you gain a fuller understanding of fuel and ignition requirements, all your trims and enrichments, boost set up etc, they also do full video demonstrations on all aspects of tuning on many different platforms and those videos are available to watch over and over.
  6. Pity no wideband. Would help tell you the full story. I wouldn't worry about retuning it all if your happy with it the rest of the time.
  7. Don't buy a $60 IACV. Been there done that for research purpose. It did not fit as advertised and when I started fiddling about with it, it flew apart in my hands. Do you have a wideband on the car? It is not picking up in the logs. CLL corr is up to -4% at idle. Don't be to quick to blame the IACV. The best thing you can do is retune the whole thing in open loop using the base position table. The Link help files are quite comprehensive covering this.
  8. I was having the same sort of issues. Try changing your stepper reset to key off and make sure you are turning the car right off if you load a new map before a start and let the needles do their sweep on the dash. The stepper motor doesn't know where it is in the V5/6 so you have to reset it. Have a look at the help file for how to set the stepper min/max values. Turn your idle ignition table off to do this idle calibration. Once you have it good turn it back on - but your idle ignition table is set to take over at below 1200rpm in the 70-80*c range, so you are dropping from 18 deg commanded in the main ignition table to between -2.5 to 2.5deg ignition. If you have 18* commanded in the main table for idle, 18* should be at the 0 column in the idle table and higher and lower values either side of it and it will then dither either side of the centre to keep your idle at the target rpm providing you have it set up nicely with your stepper motor and AFR first. EG 12-15-18-21-23
  9. If you extend the log right out there is some data right toward the end. It is idling in the one same cell hence the data in the mixture map being in one cell. Maybe you woke up the tablet before you parked up and turned the car off
  10. Hope you get it sorted ok mate you shouldn't have too much trouble finding someone in Melbourne
  11. What engine by the way, Subaru???
  12. Is the turbo too small? It's not holding boost There are huge swings in Lambda at cruise from very lean to very rich. Quite frankly Lambda is way off its targets almost all of the time. Probably due to the large jumps in the fuel table between load points. At one point in cruise it is as high as 1.2 (17afr) @3000 rpm at steady throttle. It is also very lean at times in boost like .956 (13.8afr) @18psi. Just two examples of a constant theme. For some reason it has 2 x Lambda Target Tables on one fuel type. Generally 2* timing comes out for every 20kpa (3psi) load. Have a look at the ignition table - It's just sitting there in big blocks of the same and higher numbers. The CLL is turned on with 0 gain and it doesn't seem to be making any corrections although the fuelling needs to be pretty close for it to work well anyway. Put Lambda avg and Lambda Target together in your logging time plot and you'll see what's happening. The knock control is turned off so we can't see what is going on there.

    On petrol it will be in the range of 190-220kw atw depending on how hard you push it
  14. For your cold start use the Warm Up Enrichment table. Get your Lambda where the car is happiest at warm idle somewhere between .9 and 1.0 Start the car cold and follow it through the Warm up Enrichment table adjusting the values to suit whatever the car likes. Don't be set on a number. It may want to be richer than .9 on it way up in temperature. It will take more than one cold start to get it really nice. That is a start point. I found to get it real nice it is a combination IAC control and Lambda over a period of time.
  15. What a beast mate.
