TD_D mod journey. From stock to the 'bastardmobile'

Okay cool... Is the controller taking full control of the turbo boost or is it working in combination with the ECU.

I ask this because the wastegate and turbo dynamics setting in the ECU look strange to me.

I think the controller fully handles all the turbo dynamics - bypassing the ECU. I'll double check.

 

[HolyCrapItsFast]

That would actually be good.

Okay I'll have a look

 

[HolyCrapItsFast]

Alright - here it is - http://dl.dropbox.com/u/3099895/TD_D_8_Feb_loga.zip

Uhmmm. These are the previous logs. I have them already.

 

[Td_d]

Sorry - not sure what happened there - Dropbox seems to have created 2 copies - this one should have log21 in it.

Here's the manual for the boost controller - just checking to see the exact functionality:

[Td_d]

Ok - what I can see from the manual, the e-boost street 40 pretty much takes over all functionality in terms of boost control.

 

[HolyCrapItsFast]

Okay thank you!

I kinda figured that. The settings in your ecu would blow up a normal car. And that you have a honken turbo it would make matters worse.

I'll keep you posted on the logs.

 

[HolyCrapItsFast]

Okey dokey. Here is the last one for now. It takes care of the last idle trim errors and addresses a little bit of knock that showed up around +3 load and rpm above 3000.

If you could take one more log, to just confirm this one and to take a quick look at tip-in enrichment, that would be great. Then I think we're ready to move into open loop!!!

Yay! :tard:

Okeydokes - here they are: http://dl.dropbox.com/u/3099895/TD_D_9_Feb_loga.rar

Working on getting an Innovate LC-1, I really hope I can get it in the next day or 2 so we can move to open loop.

 

[HolyCrapItsFast]

Hmmm, Very odd. I'm still not happy with idle trims. It's almost like the changes made no effect.

Are you sure you flashed rom 750rc_2-08-2011-Rev_B.hex?

 

[Td_d]

Positive - let me double check on the notebook now, but I'm certain I did. I did notice with this Rom, there's an odd 'hesitation' as you crank up.

Another question - there's been a pervasive smell of raw gas from the front (I know under the bonnet, since it comes in through the vents) - would that be the super rich idles (it has been much less noticeable over the various Roms, but still slightly there) - or could there be, for lack of a better expression, a leak somewhere?

 

[Td_d]

Yup - RevB for certain - last loaded file on EcuFlash.

 

[HolyCrapItsFast]

Okay... Then I'm gona make another adjustment to idle trims.

 

[Td_d]

Ok - there's an LC-1 in stock, hopefully I can pick it up in the next day or two, so we can nail the open loop. Now that I'm beginning to get my head around the AFRs and MAF scaling in the closed loop part of the maps, I'm struggling to get my head around how the meth with its different stoichiometric AFR fits into the picture...

 

[HolyCrapItsFast]

My advice to you is not to try to put your head around it in terms of AFR but think of it in terms of lambda. The best explaination I can give you is this one.... http://www.igotasti.com/vBforum/sho...39-333whp-411wtq&p=10861&viewfull=1#post10861 and this one... http://www.igotasti.com/vBforum/showthread.php?205-All-about-E85&p=2193&viewfull=1#post2193.

The explanation is similar for any fuel other than gasoline in that the stoichiometric AFR of any fuel is a lambda of 1.00.

Just look at your AFR's as if you where using straight gasoline and you will be fine. The danger comes when you have tuned for meth and then it fails. The mixture suddenly becomes lean if you don't have a proper meth kit with a fail safe system. It's important to monitor at all times.

It is probably in your interest to have a no-meth tune as well in the event it fails long term. The way to do this is to go through the steps we just did without the meth system active.

And for god sakes go to sleep!!! It's like 1:30 over there :rofl:

 

[HolyCrapItsFast]

Okay here's yet another... try this one and Hopefully this will finally iron out the god damn idle trims. As long as they stay with in +/- 6% I'm good :tup:

Thanks - will read up - so for example, a rich AFR (whether stoichiometric is 14.7 or 9.76 etc. would be under 1 and vice versa). Ok - I'm really intereted to see how this plays out in the open loop turning in terms of the fuel maps. And yes - the system most definately has a failsafe - it will drop to wastegate pressure immediately (it's also a PWM system similar to the aquamists)

And for god sakes go to sleep!!! It's like 1:30 over there :rofl:

Chuckle, yes it was... sleeping early was never a strong point! As is coffee a serious requirement in the mornings!

Thanks for the new map - will test drive it today, hope that puts closed loop to rest.

Ok - I should have the LC-1 tomorrow, shop went to pick it up this afternoon - here are some logs, in case, she's driving nicely though. Only thing is the well known 'stumble' at around 3000rpms - it feels like it the transition between CL and OL.

[Td_d]

Okeydokes - shop's got the LC-1, will go and pick up tomorrow, maybe I can get some open loop tuning done this weekend. Notebook and Romraider, here we come! ;-)

Okay I will take a look and see if I can address the issue.

Do you think you could take one log of only this condition when you see the stumble?

 

[Td_d]

Sure, let me see if I can isolate it.
