Evo 8 ECU In 2g Works!!

[hediki12]

Theres not much that the standard V7 patch changed except for a few little features with boost control and the larger tables which you wont need close to the load numbers they supply so scale them down and convert the tables using your old values and fill in between smoothing out the graphs in the process and you wont have a problem. I havent messed with the SD patch yet because I dont have the sensors.

umm i mean the adjusting boost and boost based gear , ect ect. i know its not hard just havent looked in to it in detail since i cant realy apply it yet...

So i tried logging wgdcc and it stayed at 63.5 just like hideki's anyone else experience this?

ok "good" to see my car isnt the only one.... i thought it was just bad sensor or something... btw im out the dsm game...

 

[the_mork]

Sold, broke, or totaled?

FWIW I've never bothered to log wgdcc. Basically I started tuning boost with WGDC and had correction turned off. I've never bothered to turn it back on.

Dam i hope you got something better! And im in the same boat as mork just set my wgdc and im good.

totaled yesterday.. smfh.. parting it out have some parts i never installed. looking for an evo

 

[clockworktoy]

Sucks to hear the cars totaled but that evo will be plenty fun. On another note anyone using the fpr solenoid as a bcs have any problems with opening up completely on random occasions?

 

[the_mork]

Opening up as in WOT? Or opening up as in losing all boost pressure? Or bleeding off all pressure so you overboost?

I used to have an issue with overboosting but it turned out I just didn't understand boost tuning and was going about it backwards and missing out on all of it because of error correction.

As for issues while going WOT I never had any but at this point I'm actually starting to think that the FPRs is a poor BCS if you don't have SD because it vents to the atmoshpere, nowhere near like a bov and really smaller than even small vacuum leaks but it may be something that can be modifiable. Then again it is an amount that you can pretty much tune for, you'll never open it in closed loop and at a given load the amount of air venting should be pretty constant.

 

[clockworktoy]

I had it backwards in my previous post. It stays closed and doesn't bleed any air no matter if its at WOT or cruise trying to create some boost. For example last night on my way home i was getting on the fwy here and couldn't get over 7psi (wg spring pressure) in any gear. Then after i get off the fwy i was able to create my set boost levels again so im assuming the solenoid didn't bleed any of the air out and caused me to run wg pressure. And i did think about the air thats being vented but that shouldn't be a problem for someone with a stockish intake pipe with the nipple for the stock bcs. Im thinking i might just have a bad solenoid since my connections seem solid and the lines are all fine.

 

[the_mork]

It sounds like a bad solenoid BUT try swapping the wires, maybe the FPRs is sensitive to polarity?

Did you modify the FPRs so that you could hook the exhaust port up to your intake?

On evolutionm.net they talked about the evo EGR solenoid working as a good boost controller and the only advantage I see there is the ability to recirculate the exhausted pressure. I have no idea if the DSM EGR solenoid is similar though I'll take a look at it next time I have my hood open.

 

[clockworktoy]

That's what came to mind, ill try switching around the wires and if not i think i have a spare solenoid in my garage. I didn't recirculate it back into my intake (im running an FP intake without the port) but like i said its simple enough on a stock or stockish intake.

I finally put v7 on my car tonight. I tried switching all the 2g MAF stuff over (Baro Comp, filtering, MAF Comp, etc) in hopes that my tune won't vary as much with the weather.

Last weekend when the temps dropped into the low 30s, I was running lean because the MAF was reading wrong. To top it all off, "less air" dropped me into lower load cells, so I was also running more timing. **Knock Hell** until the car fully warmed up and I got into stop and go traffic (air temps went up).

I was trying to get the low Hz stuff dialed in tonight while parked at a local supermarket. My laptop went dead, and as I was leaving, I passed a cop on the way into the parking lot. Someone may not have appreciated me revving in the parking lot for half an hour.

I was hoping to get it dialed in tonight because I have a 3 hour drive home from college tomorrow.

 

[clockworktoy]

Decided to swap out the solenoid for another one i had laying around about 30 minutes ago. Hope that was the problem.

Bad solenoid was my problem, everything seemed fine today. Gotta see how much the gear dependent boost will help my ET's at the track on saturday!

Ok, so I've been thinking about taking my car to the track soon. However, I noticed that the stationary rev limiter is not working. I remember that somewhere in this (massive 30 page long) thread, someone talked about some wiring changes to make this work.

Does anyone recall those changes?

Yep i posted up the instructions. You need to cut the wire going to pin 43 and then splice the ecu side of that into the red/black wire on the cruise control switch. Then just make the changes to your startionary rev limiter in ecuflash and enjoy.

Does anyone have the rpm/speed to gear settings for a 2g fwd? Or can they point me in the right direction to figure it out myself?

 

[Boosted3s]

Anyone have a somewhat stock evo8 rom with the immobilizer disabled? I just want to get the car to run on the evo 8 ecu with something like this before I move on to the tephramod stuff.

hey did you get it ? honestly its not that hard.. . you can run 9653, 9417 ect... and get the periferary table open the faa table and bit 3 set 0

Periphery Configuration - EvoEcu
Downloads - EvoEcu

btw guys ill b back in the dsm world soon . evos are way more expensive than i realized. . not spending the next 5 years paying for a 4g63t with 4doors. . so yea.... cant wait!!!

No suprise.

You had practice on the first car. Now you can do it right.

I wish I could afford a clean car to just start over on.

 

[the_mork]

Boosted, I can help you out in a little bit. I just got a new laptop so I'll start making roms for different scenarios.

Ok, so I wired pin 43 to the cruise control switch, and now the 2-step works perfect. However, NLTS - not so well. When i turn it on, it just seems to randomly cut fuel in mid acceleration (even when I'm completely off the clutch). Any ideas on this? Anyone have NLTS working on 96530006?

 

[clockworktoy]

What version tephra mod are you using? I remember at least a few of the patches had errors that were fixed by later versions of the patch. I haven't tried NLTS with my v7 patch yet but when i was using 5.10 i never had a problem.

 

[hediki12]

has anyone passed inspection lately with the evo8 ecu? and what kind was it was it the "dyno" or them just plugging it in? and how did you pass?

 

[knochgoon24]

I'll be going in for inspection sometime this week. My inspection ran out the end of October. I had an exhaust leak I had to get fixed first. Around here, I'm not even sure they plug it in. I don't have emissions in my county.

EDIT:
I'm getting fed up dealing with trying to get the 2g MAF working flawlessly with the evo 8 ECU. It has it's good days, and it has it's really bad days. I think I'm going to order the stuff to convert to SD this week and get it over with.

For those of you running SD, what MAP and IAT sensors are you using (Omni, JDM, GM/Delphi, Ebay special, etc)? Also, are you using the VE tables in the stock SD roms to start off, or are you using some other VE map because of cam differences?

Yeah, I just passed smog and OBD-II inspection with my Evo 8 ECU. There is some additional OBD-II Inspection code that needs to be put into the XML. I don't have it with me now, If you PM me I can send it to you from my work comp.

What version tephra mod are you using? I remember at least a few of the patches had errors that were fixed by later versions of the patch. I haven't tried NLTS with my v7 patch yet but when i was using 5.10 i never had a problem.

Hmmm..interesting. I'm not even really sure what version of tephra mod I'm running. Stupid question, but how would I upgrade to tephra v10? How do you upgrade?

 

[knochgoon24]

Tephra v5.10 was put out a while back.
Tephra v7 is more recent.

And on another note:
I finally go around to reading New thread for Speed Density tuning?... - evolutionm.net and things are starting to make sense. From what I'm reading, I should just use the stock Evo 8 MAF settings, and then adjust the VE tables to get it all squared away.

If someone else tells me what sensors they have, I might get those same ones so that we can compare numbers.
