Evo 8 ECU In 2g Works!!

[clockworktoy]

Got a rear o2 heater circuit CEL friday night, really weird but im going to look into it since i already have the patch applied.

 

[knochgoon24]

So, I'm going through comparing the Evo 9055 rom to the 2g 2055 rom, and I've noticed a few differences that people haven't seemed to have mentioned. I'm not sure if they matter or not.

The ISCV initial step position maps differ a good bit. I'm not sure where they get used in calculations, but maybe someone who knows more would shine some light on this. They differ in some cells by more than 300% Also, the Evo ones decrease values from neutral into drive. The 2g ones increase from neutral to drive.

Jrohner I'm wondering if you could shed some light on this (or anyone else).

I'm playing around with controlling boost with my FPR solenoid and things seem to be working just fine except that I am spiking pretty badly. The spike doesn't matter so much because I'm targeting about 17psi for low gears and it is only spiking to about 23psi but what I really want to avoid breaking traction at the track when it happens.

I'm not terribly familiar with the evo boost control system so I'm really just poking at it with a sharp stick and hoping it doesn't wake up and bite me. I suspect I'm supposed to do something with the base WGDC. I'm using MrFreds direct boost control with Tephra's gear based boost maps.

I've done a bunch of reading and I'll be doing a bunch more but if someone could point me in the right direction for dealing with the spike then that would be helpful.


Also I did some searching and I can't find much information on what a launch map should look like, anyone want to post theirs or give me some general pointers?

The 9055(Evo7?) and the 2055 use a different cpu and board. It might be better to compare the DSMs with the EVO5/6(same cpu), then the EVO5/6 to the newer EVOs. I think anything newer then the Evo3 used different ISC Motors then the DSMs also.

Disable correction, then adjust the base WGDC until you get your desired boost curve. I haven't even reenabled corrections yet, I just run the base WGDC and it works great. I'm sure with a large variance in temperature, the correction will be necessary though.

Make sure you have the hoses on the solenoid correctly. The hoses should be hooked up so that when it's off (0% WGDC) or unplugged, pressure should be allowed to go from the boost source to the wastegate. When on (100% WGDC), it should vent the wastegate side to atmosphere, blocking off the boost source. You can test it by trying to blow through each port, and then connect it to a battery charger (set on 6 Volt I believe) and check each port again.

 

[the_mork]

I have it set up as boost goes in where the manifold reference went in and the wastegate is connected to the port that the FPR was. I'll try to test it later but I think this is right for racing today. I don't have time to fiddle with it anymore so I guess I'll live with the spike for now.

Does anyone else feel like it might be time to start splitting up the topics in this thread so that they are easily searchable? It might even be nice to see if the mods might agree to an ecu reflashing sub-forum since so much information crosses over between this ecu and the H8 stuff.

IMO this thread should maybe be encouraged to stay on a basic topic of physical implementation and getting cars to run as well as basic technical issues. We can then have a different thread for tuning with a flashed ecu, boost control, general other computer mods, etc.

Thoughts?

I second this motion.

I 3rd it.

Read this thread for better information on scaling for a 2g maf. It also has lots of other cool and pertinent information.

[clockworktoy]

I agree with splitting the thread. 22 pages gets kinda long when your looking for specific posts. And to the guys who are using the stock fpr as a 3 port boost controller, does the top part of the solenoid (with the emblem) vent? I never really payed much attention to it before i removed it.

After further delving into my knock problems, I realize that I just copied the addresses for the knock multipliers from the 9653 rom into my 9055 file. This is NOT GOOD.

It explains why my mid was reading 61 while low was 13 and high 17.

I found the knock load address for 9055 while searching on evom. Plug this into your xml.

<table name="Knock Load" category="Knock Control" address="407e" type="2D" 	level="2" scaling="Load8">
		<table name="X" address="4d76" type="X Axis" elements="10" 		scaling="RPM"/>
	</table>

And the multiplier addresses:

Adders are two single values:
177c = 7 (triple gain)
1780 = 2 (single gain)

Multipliers are three values:
21DC = 20
24A8 = 18
177A = 13

So use this in the 9055 rom to correctly see your multipliers.

<table name="Knock Multiplier - Low RPM" category="Knock Control" 	address="177a" type="1D" level="1" scaling="uint16"/>

	<table name="Knock Multiplier - Mid RPM" category="Knock Control" 	address="24a8" type="1D" level="1" scaling="uint16"/>

	<table name="Knock Multiplier - High RPM" category="Knock Control" 	address="21dc" type="1D" level="1" scaling="uint16"/>

I take no credit for this. jcabanks on evom gets all the credit. I just searched.

Here's some good reading: Knock control - load vs RPM table found - evolutionm.net

How is 9055 working for you? I played with it for a bit and it was problem free but it always felt much slower than 9653. I'd be interested to hear if anyone else came to the same conclusion. As it is I'm not sure there is any advantage in 9055 anymore since 9653 has become heavily supported recently.

 

[knochgoon24]

The 9653 did feel faster down low when I ran it for a short time. I'll probably try it out again here shortly. My big reason for switching to 9055 was my inability to properly setup my roms due to newbish-ness.
I got the 9055 to kinda work sooner than the 9653.

Still, I had my 9055 rom all messed up, and it wasn't until last night that I finally got it all figured out. My next goal is to try getting the 9653 rom to work.

I have new injectors. new fuel pump, and new rotors, new pads and a few other odd ball projects to get done next week. I'd try running it tonight, but I have almost 750 miles of driving to do between Thurs and Sunday.

I did manage to run the 9055 rom for more than 1200 miles already.

My plan is to get the car running 20+psi by August 8th for the big NE DSM meet.

Hey quick question I'm looking @ my 2g harnes and there is no pin 46 ( looking @ it from the back were the wires stick out) I hope that the right way of goin about this . Umm so I'm lookin @ the pin out diagram n its stuff for a/t since I have a m/t is that the reason there missing?

 

[hediki12]

got my ecu in!! flashed it took the stock rom off... but because the car was dead and the booster pack barley had juice so the car wouldn't start. is it normal for the car to crank with out the ecu disabled? i did disable it but i just want to make sure.. thanks guys for all your help!!!

 

[the_mork]

I'm not sure what you mean by the ecu disabled, did you mean the immobilizer disabled? If so then yes the car will crank with the immobilizer on it just wont start. If you are using a Tephra rom then to start with I would make sure that valet mode is disabled, you could play with that later but for now just turn it off completely.

 

[knochgoon24]

Yeah. It will crank and crank but won't start if the immobilizer is still enabled.

EDIT: Jeez, it sits unanswered for 8 hours then we both answer at the same time.

 

[hediki12]

yea im using tephra 9653 (wish i knew how to get back the original 9653) and since my battery was dead and i changed my alt im trying to start the car with the ecu. flashed it and all... but it just wont start jumper pack keeps dieing.. so im waiting till i can get some one with a car to come see if its just more juice i need. also check out if the immobilizer on this rom is disabled thanks!!!

Looks like you have it disabled alright.

I think this should be a clean 9653 rom. Change the elg to hex.

 

[the_mork]

Perhaps at some point we should create and host a rom that works for a stock car and put it in the first post. I'd volunteer but I just got a new laptop today that I'm setting up then I'll be out of town for a week.

 

[hediki12]

ok im tryin to start my car just wont start... plugs r getting no spark

Can anyone shed some more light on using the fpr solenoid? PM me or post on here, thanks.

 

[hediki12]

can some one send me a. 9563 rom that's already immobilized? I don't care if it is tuned ill return it to stock values.... I honestly think I'm retarded. Because I can swqap pins and no de-immobilize an ecu... no spark is comming through the plugs so I'm guessing that its immobilized..
