Man I'm mad jelly of you two

I'm trying to figure out how to sort out this 20i curse without voiding warranty... Not looking good

Wow...that map 6 run looks very good to me. You must be using e85. Timing is very good. Dropping throttle is probably due to boost control.

typical run for me is 560rpm/sec....yours is 650 rpm per sec....not bad

Good news. Mine is out for delivery. But I don't think I'll be able to install it until tomorrow since I need to take the baby out and the SQ5 it is
I'm guessing the pins go in the same holes as mentioned in Terry's install guide for the N55 (purple/9 and blue/16).

And yes. E85 helps apparently. I've been filling up roughly 4 gallons of e85 and 11 of 93.

Hehe if soldering was involved, it would've been goodbye to the EWG connector! Do I run the same settings you sent in the last post after the connector is installed?

Higher rpm/sec means faster I assume? Or is it something else. Total noob question I know.

Yes same settings

Might be able to run an absolute target but let's do one step at a time

Yes it's just change in speed over time

Not the best metric in the world given its a bit ambiguous what gear you're in AND ignores which part of the Rev range

Best way is to do single gear time difference between speeds (relatively high speed and long ish time duration), get a somewhat accurate weight, and cda figure (you can get this experimentally but online figures are pretty good) and you can fairly accurate estimate wheel power (this is effectively what that spreadsheet I made is for

Yes. In general, since I run the same gear on WOTs as you, and we have identical car setups. Assuming similar road conditions and weather. That said, i have never had that type of acceleration on mine...your timing is the key here.

Ah gotcha KnifeEdge87 and Turboh. I still don't know how to read logs too well except for timing drops and boost.
Got the EWG cable and checked the plug in my car. Both seem to be the same. So it'll fit. Next step will be to install the cable in the box tonight and maybe get it back in the car tomorrow for some runs hopefully. But it's cold here and raining. So yes.

Hey guys

I installed the EWG connector.

Do I need to change any settings in the custom values? Or run the car with the same settings as before? Any settings for the EWG connector I need to enable/disable?

I ran the car on map 4 (absolute 20psi) and the custom map 6 (settings below). Map 4 didn't feel punchy at all. Map 6 felt like before. But the throttle looks weird in the logs. It was smooth without the EWG cable. Wonder why?

4 is not as aggressive as 6 which goes to show how far we got with map6 (and the fact you have E85) alone

What we should focus on is turning our map6 additive into a map6 absolute setting now

yea u are geting some throttling issues (and DMEBT backing off from what you had before)

is this on a diff tank of gas ?

Any other conditions different worth mentioning ?

Ambient temperature ?

I saw you posted another topic about an issue you had with installation but i didnt get through it yet, has that been resolved ?

In the meantime lemme give you new absolute for map6

1500 14
2000 15.5
2500 18
3000 19
3500 19
4000 20
4500 20.5
5000 20.5

the throttling seems to all be from ECU PSI approaching DME BT

I'm not sure if the absolute map6 will help but if I were you I'd try this first before we bug Ando and Terry it's quite difficult to ... keep their attention =D

Good thing is that it's not from an Octane/Timing/Knock issue so we're safe to keep tinkering on our own for now.

FWIW the blue line in above charts are the actual manafold pressures (boost 2) from your P58_M6_R1_201014_log4thgear.csv

Btw ... did i mention I'm mad jelly ?

I tried to back out what your WHP is now but i couldn't get the numbers to match up

do you know your gear ratios and final drive ?

Can you also provide your wheel/tyre sizing ?

man you're still pulling something like 0.25Gs accel at the top of 4th

Those are some damn good numbers man

By my count that works out to roughly 270-280whp give or take(super rough numbers)

Heya!

I went through your posts and my answers are below:

1. Yes. I had to fill up the day before I installed the EWG since it was extremely low on fuel. I did the usual (2gallons E85 with 6 gallons 93oct). The mixture is roughly E29-30 but I haven't ever measured the actual ethanol content of E85 here. Regarding ambient temp, it's been cold here the past few days. The logs without the EWG were sent on slightly warmer days I believe. With the EWG, temps were around 45F.

2. Map 4 felt much weaker than your custom map 6. So much so that after driving around for a minute or two and then logging, I went straight back to map 6 again.

3. The throttling is present only after I installed the EWG cable. I've sent you logs without that and it looked perfect without any throttling. But car doesn't feel different or it doesn't feel like it's being throttled. Just in logs.

3. Hehe. Maybe you should swap your 20i for a 30i. Or a different ecu should work? :D

4. I did search for my gear ratios and stuff online while setting up virtual dyno. I had to add my car to it since it wasn't present. The values are in the photo below. Wheels are 225/45R18.

5. According to Virtual dyno, highest I got was 295whp with the latest custom map 6. Lowest I got was 280. I had three logs to try and it was 280/285/290whp with the last map you sent.

1 seems ok then
2 yes, as it should, new map 6abs should be superior to map 4 and old map 6
3 it's retarded in Hong Kong the 30i costs like 25kusd more than the 20i
4&5) seems you got it sorted out, and god damn I'm jelly, tempted to stop helping out now =P kidding.

Power of E85, I can't hope to get anything close to what you're getting unless I get WMI, even then that's not really as good as E85. Best we get in Hong Kong is 98RON

Yes 98 ron is like 91? I forgot my conversions.

And I know. These cars cost crazy money in india too! A 330i is like 85k usd.

And no hopes for logs today. It's snowing here. Ffs. Can't wait to try the absolute map. Hehe

I managed to get some logs (?) today. It was freezing. Lots of wheel spin when trying WOT especially from a standstill. I had the latest settings (post #111)

We're almost at the limit now

We can get more midrange but top end we're basically there (trims hanging around 44 now, we don't want to see this too high consistently). It's not because bad timing or whatever, it's because of fueling limitations. Soon we're going to run into bottleneck of the fuel pump just not being able to keep up.

This will need hardware modification to rectify, it is true that you're getting a bit more throttling now which is coming from ecupsi vs dmebt, this has to do with the speed and the logic the JB4 uses to trick the ECU

JB4 needs to react to change in DME BT by sending a false ECU PSI signal, if the JB4 isn't fast enough or cant predict enough, it might send an ECU PSI signal that's too close to a new DME BT figure causing the ecu to throttle close, will need to check with the BMS guys if there's anything to do to improve things in this area

Ah yes. I understand.

And I think you're right about the fuel pump not being able to keep up. I did get an error code 11605 that I've gotten twice before (though that was when fuel level was 1 gallon or less). This time around, I had half a tank of fuel. Happened after a WOT run on the highway. Car doesn't go into limp mode or anything. No CEL. Just a drivetrain malfunction saying I can continue driving normally. Turned car off and cleared the code and it didn't reappear.

As long as the throttling doesn't cause a problem, I'm not worried about it. Just that all the graphs I've seen show perfect throttle values (almost same as pedal values) and I wonder why my car doesn't do the same (it did before the EWG connector).

Again with the latest map. The difference is as noticeable. In fact, so noticeable that after the car had warmed up and I did a WOT run, I actually said "Oh wow!!". It was that obvious. The top end is great. Midrange isn't bad at all either. But you said we can get more midrange :D I don't mind trying as long as it doesn't blow the engine up. Hehe. Even now, it feels good!

I'm so grateful for all the help. I'll try get some better logs if the temps rise but I'm guessing that isn't needed with the same values?

Would like to get logs with warmer ambient temps

Again, we don't want to push too far simply because it's winter then find out we edged it too much come spring /summer

I totally agree. Hopefully temps go up soon. It's supposed to become warmer in a week or so. Today was bad for WOTs. All four wheels spun all through the rev range in first and a bit in second because of how slippery it was even though it didn't look like it. But yes. You've made my car lively!

LOL...you are cold!

FYI..JB4 Duty Bias FF Tuning Info - Page 7 - N54Tech.com - International Turbo Racing Discussion
is a good link on DB tuning. I am getting the wire this week and will play with it after that.

Looking at your logs, especially the recent ones on V18 and with the wire, I did notice that engine temperatures were on the cool side. I do know from my previous B58 that if the engine is not up to temperature, boosting will be compromised by the ECU.

Also, glad to see you got your VD running. I have not looked at you VD settings yet, but your readings are close to mine...Good runs for me are in the 280-290 range. That said, i do not use any additive in the 93 octane gas.

It is hard to compare WHP like this but it does give you a sense of improvement. Check the link...it is quite interesting. Screenshot of my VD setting is attached.

Hehe yes. It was around 36F when I did the runs yesterday. Same temps today too unfortunately. Plus rains like yesterday playing spoilsport.
And I hope the temp is what I causing throttling issues. I do remember weird throttling issues earlier this year too when I just got the JB4 and it was freezing.

Our VD settings are similar except your tyres seem smaller (?). I'm running stock 225/45/18s. I guess you have 255s and 19s? Did you do a log on map 0 for VD to see what numbers your car put out? Mine was extremely low on map 0 (225whp/246wlbft). Which also reflected in times (on map 0, quarter mile was 14.0s at 99mph using a dragy).

And for sure. Let me know how your car feels after install. Thank God the install is a breeze in our B46s. Would love to hear your findings.
