This really makes me want to revisit E85. Those numbers are noice. Did you end up going with the target boost table with E85 % on the Y axis or did you go with 2 separate boost maps.

Short and sweet I had boost timing and fuel tables all based on e85 YES on the y-axis

Nothing different from before, just did a couple driveability checks and they all worked out so ~470/370 were the final numbers that day... that was on 20.5-21 psi

Once Dylan does the processing to the Dyno sheet I'll post that, but for now, here is a VD Graph from this morning. 3rd gear goes quick. I probably will not drive it much until thursday, I cooked a WB on the dyno and I dont like beating on it w/o it.



Did not take to redline because I'm not used to it not being 7000
Car --3260, full tank of E85.
Me --220
"stuff" - 30

Posting Dyno Graphs Here, and Making a PBB Thread that actually reflects the turbo in the name. I cannot edit it for some reason

What was the boost level? Awesome results.

Jr... What are your thought on the EFR series? Did you take a drive off the dyno? What was it like on the road?

Thanks!

Thanks Allan.

I just got back from a little cruise where I really got a chance to get on it. Did 3 pulls and it cooks.

"Only" came up as 550/440 on virtual but with the road I was on I'm not to concerned with the numbers. The curves still looked the same which is what matters to me.

From looking at my logs looks like 50-100 was 4.2 with a .5 second shift. I'll take it.

She likes to boost, you can see that. I'll bet it feels great!

13.2 mpg on first tank giving it hell Haha not bad!

It feels good just to drive this car and be happy. I know good things come to an end and the mod bug will hit again and things will break but for right now this is just awesome.

I hope there are some people subscribed to this that can help me out with this question.

Dyno day last week... hot and miserable. Base fuel pressure 55 psi.

In my garage it stays about 66-72 degrees depending on the temperature outside. When I prime the pumps I see 43-46 psi and it slowly climbs up to 55 as the fuel gets warmer, which isn't very long due to the surge tank, probably 15 miles and its normal. I stay out of boost a byways because of cold oil but I'm mildly confused / concerned

What are your guys thoughts on this? It does take a longggg time to start, was thinking about playing with the startup tables once i have some time. Haven't noticed if it needs more or less fuel.

I told you about the start up issues I had with the fuel pressure reg that wouldn't hold pressure after shutdown and delayed start because it bled pressure so fast that the pump prime decayed almost instantly. When the engine caught and was running, fuel pressure was fine though. Its odd that your fuel pressure starts out low and climbs to 55 over a 15 minute period. What are you logging for fuel temp during that period? Are you sure your fuel pressure gauge isn't very temperature sensitive to engine bay fluctuation.

Yeah I remember that. It is honestly a second or less to hit whatever fuel pressure the FPR is holding at that given time.

I didnt think to check out the fuel temp... mostly because I feel that it would be inaccurate because my surge tank fuel is going to be a lot warmer than the bulk tank. Even though it is hooked up via the OEM sending unit I am not sure the values are right; however I can check that this morning where I know exactly what the fuel temperature is (ambient temp in garage)

Edit** went to check fuel temperature this morning and there is no way to get it on the link right now. There is in ethanol temperature sensor and it said negative 50 degrees Celsius... I need to find out where that center is which it should be in the ethanol percent sensor but I need to find it and calibrate it so that it will work then it would be right in line with the fuel system.

Isn't your flex fuel overlay table spanned ethanol % vs. Ethanol temp?

Nope. Right now by MGP. It is basically a 2D table right now, for a given E% It is static across all the MGP, which makes sense.

The Ethanol sensor has a built in temp sensor also, but it is a frequency vs a voltage, and I am not sure if the Link has the ability to pull frequency.

I loaded up the base map, and I didn't see the OEM Fuel temperature location either... Maybe it is ANTemp4 that isn't visible on the pinout?!

If you have your E85 sensor hooked up as a digital input channel it calculates E85% and E85 temp. Hit R and pull up runtime values and check the fuel tab. E85% is a digital PWM signal too that comes in on the same channel as temp and is derived by the ECU.

I'm not understanding your flex fuel map. Isn't the main fuel table spanned MGP vs. RPM with either a 4D, 5D or dual fuel overlay table spanned E85% vs E85 temp? That's how I've seen it done before and what I've picked up from the Link forums but I'm sure there are other ways to get it done.

I pulled up the run time values, there was nothing ethanol related under fuel.
Under the calculated tab, I see ethanol % and ethanol temp. Cool... except for it says 132 C. This was just pulling up my map at work. Not real time.

As for the table, that could be and probably is the proper way to do it, but currently it isn't that way.

I wonder if the Siemens sensor is a little different than the continental? Its supposed to be the same functionality wise, but maybe its not. I changed the wiring over to the continental wiring last night, but it didn't change any content.

They're all the same sensor or use the same flex fuel protocol. You need to look at the values live with fuel flowing through them to get current info. Depending on how your lines are run with the car off the return line can be empty or close to empty since the pump isn't running. If you have some saved logs you can check ethanol temp from logs when the car was running.

Runtime values are only valid when you online with the ECU

I have my 044s on the key switch to prime, I'll check tonight. I've never looked at old logs.. Unfortunately, they said 132 degrees, but this was setup w/ the external pull up, so I'll have to check tonight to see if it changed.

Scary **** last night - I was worried I blew something up. Accelerating from a light last night on a bumpy road, and all the sudden my car just lost power, went lean and could barely run under its own power.

I tried lookimg at the fuel lines, actually hardwired the 255 and checked all vacuum lines ... still no dice. My buddy rich asked if I could check for spark from the Link and I said Yepp..

As I was connecting, he noticed that the passenger front (cylinder 1?) Had the spark plug wire disconnected ... the damn coil pack broke. Thankfully Erocs04sti had a couple for me, and gonna ship them out first thing Monday. ... which led to spending some more money also - DSS front axle bars .

Car lost 6-8 pounds today between intercooler sprayer and the middle seat belt in the rear... don't need that juuunk!
