trying to get a base map setup. Just to make sure, i can change load8 to psia8 to make this psi based instead of load based on the Boost Desired Engine Load table?

 

Gotcha, I have AFR min and AFR max. They should be volts min and volts max. How does one change the XML to read that?

 

tephras definiton xml attached to the download will give you all that you need.

 

Am i missing something? I see Baseline WGDC and Boost desired engine load. I need a Baseline or Target Boost table instead of Boost Desired Engine load. Can i just change the BDEL table to PSI instead of Load?

 

Make sure you are in developer mode.

 

I am, i want to validate that changing the BDEL table from load8 to psia8 is correct.

 

Mike - yes - you still need to do the replacement of ROM locations with the MAP sensor signal thou... But yes changing the scaling on the tables will convert them into psi based.

Dan add the following to your TephraMod-88590615.xml:

That should add new tables for AFR...

 

it has been a long day... So as long as i change it to psia and set up the rest of the direct boost control stuff per mrfred's thread then i should be all set.

I will play more tomorrow.

 

Yup

 

Added and thanks. Will test out ASAP.

 

I think I get what he is talking about... he is referrring to
WGDC Correction Interval (High Gear Range)
WGDC Correction Interval (Low Gear Range)

Before we realized the stock ECU had "gear dependent" boost control (just the hi/lo) we would only change the High gear range version because they other one "didn't do anything" (until we realized the boost maps were different). Do they both come into play now based on the code or do we still only use the High gear range one?

Correct. Everything still "works" the same, it is just more detailed. You perform any mods to this ROM the same as you would to any other ROM.

I should really help Tephra out and start writing up a feature list/description in the ECU wiki so we can get rid of some of these redundant questions....

 

^ that would be awesome

re - the "interval" just use the original one (#1.. not sure what it relates too)

 

I logged EGR for you guys from cold startup this morning... log is here:

http://thefrost.net/randomfiles/tuni...EGR_warmup.csv

Unfortunately I didn't log coolant temp. This was from cold startup @ ~30*F to fully warm though. I have barely any EGR, but not just 100% flat, and I'm also not sure how much it normally runs at these temps. I did modify my timing reduction vs coolant temp map, not sure if that could at all be related...

Here is an image just for loose reference, looks like a nice slope up to me...


(notice the spike right after startup, but its gone right after that). I will admit that the car has been falling flat the first time I go in reverse and then 1st, but after the short drive through my complex in 2nd I don't notice anything else.

 

Has anyone exceeded their fuel/timing loads on an alt-map? I wasn't really breaking 300s on my old injectors, but I went V6 and RC 1200 cc at the same time and my load will fall flat on its face over 300. 1 byte shows it instantly dropping down to ~2.4 the next cycle until it can fall below 300 again. I'm going to rescale later today and see if it sticks around.

 

hrmmm on main maps maybe that is why my car seems to have a "flat spot" in 3rd when i jump into it, I know im way over 300 load ( think its scaled out to 340ish) but perhaps im hitting my boost cut? (again lazy but think its set to 310ish)...


kinds like timing falls off, then it picks up effect? (or like you pull the hand brake for a couple seconds the car "bogs"?)


ill try alt maps when i need to refuel
