Yeah, the ARC2 is nice. It provides enough energy to light of a 9:1 mixture at 40psi and push stock pistons out of the engine. Ask me how I know. Thanks for offering to help people out even if many people would like to spend 2 or 3 times as much for the same or even less performance.

 

Thanks for looking at this.

I'm not sure about the EGR issue. It doesn't bother me as the EGR is disabled now. Perhaps talk to travman I'm swamped at the moment and honestly I am a moron and I forget.

What I am saying is that I don't like instantaneous. I can up the limit but the switchover is quick sometimes and it can still catch it. Its not that often but its still enough to ruin a good thing. I also run leaner than moste people . Also from time to time you will get a small spike in the voltage signal from the wideband which can cause it to trigger an event. I'm just saying that I'd like a timer so that I can edit that would make the AFR be lean for a tenth or say two tenths of a second before it pulls boost. If it is really that hard to code I'd like to keep the code as simple as possible. However I believe this is a worthwhile edit.

 

yeah I know what you mean...

ok I will see if I can put in a timer

 

Thanks man, your awesome.

 

I wonder if it would be easier to just change the input / output to the boost cut function or at least just copy it as a skeleton.

 

I'm having issues getting v7 for a 94170015 car working. I assume all that needs to be done is disable the immobilizer and it should be good to go? I've done this but, car just cranks and cranks, just like the immobilizer is incorrect.

I'm going to dig some more to make sure the immobilizer is in fact disabled but, wanted to get some input or suggestions as well for this. Thanks

 

Look for my post and download my USDM version of v7. Your problem is you have to switch over you Immobilizer HEX and your Immobilizer code. You do not have to turn off the Immb. just copy over both and you are set.

If you download my USDM version you don't have to worry about that. It's a couple pages back, just search under my name in the thread, you'll find it.

Thanks fellas. I'll give this a whirl.

 

I have questions about the launch map stuff.

1. Enable in the tephra mods section

2. Launch map TPS threshold is minimum TPS postition?

3. Launch map speed threshold is the maximim speed that the launch map will be in effect or is it the minimum? Once the speed threshold is met then the ecu switches back to the main map?

Does the code check the clutch pedal switch?

Why so much positive (atdc) timing in use? Phenem is using -20 tephra map comes with -10. Is this because the engine is not under load?

 

96530706 V7T6 is up

96530706

I have changed a few things:
- fixed altmap by adc0f
- fixed AFR check
- added timer to AFR check
- added valet disable code when altmap by tps is selected
- moved map averaging code to make room
- made the category TephraMod-V7T6 in ecuflash
- added 40 (0x28) to the MAT code

As usual, please take the usual precautions with this ROM. I have made a few changes in this ROM so there is a possibility something might be wrong

If you can all re-test everything and let me know that would be awesome. This will be the final release of V7 unless something is broken :P

 

Dan - as you can see i have implemented the AFR timer - if you can test this part that would be good.

Also - I don't think the AFR safety was working at all pre this release - so again be a bit cautious when testing

NEW XML btw

 

Would it make a differene on the 88590615 if the MUT8A was the stock value (6ACD and 6B41 for MUT8A and MUT8B intead of the modified version (6EE3 and 6EE9 respectively), for ECU boost control mods listed by mrfred?

Secondly, my car did that weird thing again, not starting randomly. I fixed the problem again by holding down the gas pedal a couple of seconds starting the car. It's the second occurance now. My car has no mechanical issues. I can't understand why this is happening. Any ideas guys?

I know we previously discussed that the 2byte load/rpm were different, but it didn't matter much because 1 byte was good enough.

The instructions by ecu boost control mods are listed and found in the link below:

"Change MUT8A will read 6ACD. Change it to 6EE3 (again enter it as 0x....)

Change MUT8B will read 6B41. Change it to 6EE9 (enter it as 0x....)"

A few things I found when playing with 96530706 v7t5 is that I wasn't making the same boost levels as I was prior to this. I am running a completely stock boost system (thanks STU ) and on 94170015 v5.1 I would make peak boost of about 20-22 psi, depending on weather conditions, however, on 96530706 v7t5 the car would only make about 15psi and would bounce between 15 and 17 psi.

I checked the boost settings within the v7t5 ROM and found a few things different in the wastegate settings but, after making the changes to reflect my 94170015 v5.1 ROM I was still having the same issues. I know there is alot more boost related stuff in the 96530706 ROM as opposed to the 94170015 ROM so I'm not quite sure what to make of it.

Another oddity I came across is the car through a PO446 code, which I've never had before. I switched back to 94170015 ROM and haven't gotten the code.

One more thing I found weird is that it seems like the launch maps were engaging as I pulled slowly from a stop with about 50% throttle and the clutch pedal half-way disengaged as the car would hesitate than go. Kind of weird.

I'll give v7t6 a try but, just wanted to report those problems to see if anyone else came across them. Onto v7t6 - to patch mrfred's SD stuff I presume we can just copy his SD related .xml for v7t5 into v7t6? Also, why is their 4 files in the download. They seem to be the same but, 2 of them start with "_," while the other 2 don't??

 

1,2,3 - Min TPS for launch to be active, yes. Check a few pages back for discussion on weather or not the code uses the clutch.

Using too negative of timing can lead to a bunch of knock and be harder on the turbine and catalytic converter. on my car I've found that beyond +5 there aren't a ton of gains, and they were all negated by tons of knock as soon as the clutch started to engage.

It shouldn't make a difference, but why wouldn't you just change them? I recommend doing the mod as posted by MrFred


Are you using the standard boost control maps or the 3d maps? I'm guessing you are using the standard (non active) maps and running ~0% WGDC. Your boost is then fluctuating because of the 100% wgdc below this load option.

You were 50% throttle with the clutch partially engaged and not launching? why? I'd say this is probably more related to tune but I could be wrong.
