Here's what the stock boost tables look like:

Boost Desired Engine Load (BDEL) on the left, Baseline WGDC (BWGDC) on the right. The high/low gear range tables use the same values.


These are my boost tables on v7. little table on the right is boost adder


(I don't recommend simply copying these maps over to your rom. I'm just posting them to give you an idea of what mine look like. I'm not responsible if you just copy them over and get a huge overboost )

 

excellent, thank you!!!

 

ok so since we are on the subject of V7 issues; there seems to be various entries in these roms that seem invalid on sight. For example:

Accel Enrichment(incorrect) - The RPM axis is set to 12850 down the line.
Max Total Upward WGDC Correction vs TPS: TPS axis ranges from 0-25000
Max total downward WGDC Correction: -64.0?

some others within GLOBAL BOOST CONTROL SETTINGS as well as tables within GLOBAL FUEL SETTINGS. Are we to leave these settings as they are. I never edited these fields to begin prior to upgrading. Anyone else having these concerns?

 

here's what the upward TPS correction table definition should look like. Right click on the table in the left list and click edit map. Make it look the same as this:


And here's the correct definition for the accel enrichment.


max downward WGDC correction is correct I think.

 

I experienced some of the same trouble. It definitely pays to do some reading! I recommend posts from tephra, mrfred, and Evo Kid (among many others).

Using load based boost control and the factory boost control solenoid, you could see your maximum capable load (depending on hardware) be the result of adding "Base Wastegate Duty" and "Boost Desired Engine Load." To my understanding, once you move to a different boost control solenoid (Grimmspeed or AC Delco 3 port type), you'll need to modify your "Base Wastegate Duty" tables to be below 100%. Someone please correct me if I'm wrong. If you then install a JDM or Omni MAP sensor, you can use TephraMOD Option 2 for PSI based boost control and use the tables (not necessarily the values) Raptord provided earlier.

For reference, I've attached the boost tables from my ROM.


Thanks,
Paul

 

Raptord; Thanks for the screenshots, they have put me at some ease. the Max total upward was totally wrong. Thanks again! (and ofcourse you are not responsible...)


ZMAN; thanks for the explanation. I have looked these tables and values up yet though I have upgraded to V7 most of the mod are not used. The only ones im actually using is Knock CEL and Rear O2 simulation. Along with some other mods like p0030 misfire code and settings for JDM MAP. Might I mention I am using an HKS Electronic Boost Controller EVC 5. My issues of fuel consumption and now recently boost limitation has fed my curiosity to check these tables. I dont do much logging because since NYC streets have gone to crap since our last snow storms and I cant afford to run into a huge pot hole while logging.

In conclusion, with a stock ix turbo and tuned on 26psi w/ meth what should the booost/fuel values be? I just want to get thing working like they were when Tephra 5.10 was out. If not then I may just downgrade to avoid the hassle.

 

Here is something else I see; can these values be correct? They sure dont look so.



The second is the CROSSOVER

 

Base WGDC doesn't go above 100%; 100% WGDC means the wastegate is fully closed and all air is going through the turbo to make it spin. Desired load is the one that can go up to 159.4, whether you're on 3-port BCS or the stock solenoid.

I'm not sure how the HKS controls boost; is it an EBC that you adjust in the car? Or just a solenoid like the grimmspeed?

And yes, of course it's not my fault the defs are wrong; I just figured out how to edit them so they display properly. For accel enrichment I just checked a stock 88590015 rom, since it's defined there also, and I noticed the RPM address wasn't the same. I changed it in the v7 rom and voila. I can't remember how I fixed upward TPS correction, but it was something similar to the enrichment table.

I have the same values; I'm fairly certain those are correct, even though they look odd.

 

So I realized that I only changed the BWGDC table to 100's, however the boost desired engine load table is still zeroed.

The car makes boost just fine, however it seems like corrections to that boost are slightly off. I just wanted to come document once again, that this table also needs copied over.

 

Raptord, thanks for all your help so far I appreciate it. My ebc can be set from the inside and it's electrically adjustable. The offset value or boost curve is set t1o 30%. How about the corrective wastegate interval. It' s set to one

 

Unfortunately I'm not familiar at all with EBC's, so I'm afraid I can't help you with that :/

 

For the rpm/speed to gear table, you need to use MRFREDs "evo gear calc" spreadsheet and your tranny type and tire size to get the correct values to enter into that table.

The second table is only used if your gonna use MITSU "gear based" boost control, which only has one crossover point and basically disabled from the factory.

 

If you have an external EBC, you dont need to mess with any of the stock ECU's boost tables except the Boost/fuel cut table.

 

Are you talking about the one specifically labeled "FUEL CUT LOAD X1" and "FUEL CUT LOAD X2"? If so these are what they look like:



The question is which one is it using? I have been limited to 93-98Kpa(14psi) all week. In some cases I boost past it and go to 150Kpa(21psi). These levels are not reached by WOT though; usually sand bagging within 3rd gear or at times from cruise in 2nd gear. I will check for leaks tommorow and would like to apply the correct value.

PS: I am tuned for Meth on 26PSI(180Kpa)

 

I just changed my "RPMSpeed to Gear" table after referring to MrFredz .pdf file. Now the TephraV7 requires an upgrade for the USDM EVO9 with 88590015 with the 88590715. This ROM ID shows the description as a 6MT and "TDM" Market but I have a USDM 2007 IX SE(5MT). Because I have a stock tranny and stock tire size; I used the following which is the 2006 5MT settings up until 5th gear and just for the sake of completion the one 6th gear entry for the 2006 MR. Is this safe to do since it will never go to gear 6 since it doesnt exist?
