Tephra V7 modded to work on a VII

[burgers22]

This works pretty well on my VII, no CELs and drives very nicely.

[Benny]

Your work burgers?
Have you changed much from the original? I had all sorts of dramas with it on mine in the original V7 form.

Wouldn't idle, jerky at low RPM etc.
Didn't spend any time on it, but yeah wasn't smooth like snake as the 90550001 was out of the box.

[burgers22]

The ROM I first used was the 2706, which is the live mapping version. This behaved in a similar way to your description, it was ziad patched 96532706 ROM.

This is just a plain vanilla 96530706, no live map, no SD, and on my car it drives rather well. All I have done is chose the periphery bits that eliminate the CELs, enable the rear heater patch, an find an imoblizer setting that works. I'd be interested to see how it works on your car, if your inclined to try it.

[sponners]

nice one Marcel, might have to try this (loving the big maps)


I dont suppose theres much feedback on evom about this?

[Benny]

I'll give it a burn when my front pipe and w/b is permanently installed.

[tscompusa]

testing this on someones evo 7 now. I'll report back what we gather.

can't wait to hear your report. i really want the big maps. burgers did u try it wit ecu boost control?

[ecktt]

ditto

[Benny]

From all reports tscompusa's customer (my mate) is having a good time with this.
No complaints so far.

Not so on my 7, idled like rubbish, hunting, fueling up badly etc.
Threw 90550001 back in and smooth as silk.

I'll just wait for 90550001 V7 I think.

[neilm]

is 90550001 V7 going to come out ?

[GrayW]

is 90550001 V7 going to come out ?

I emailed Dave about this, he's busy doing the X stuff. Maybe if people who used/wanted it made some reasonable donations he would make it more of a priority.

id be up for that im sure he takes paypal

[ecktt]

Got an e-mail to test it and replied. Waiting for Tephra to respond.

[Benny]

Yep donated a few weeks ago and he told me to sit tight for 9055001 V7. :)

Hi Benny, thanks for the feedback. Is yours a JDM VII, original ROM 98640014 or similar? Just wondering where the models may have a diffrence. When I tried Ziads version which was a 98562706 I had the same problems as you.

[Benny]

Yep 98610014 originally.
I've tried both Ziad's and yours, same result.
Its fine for a while, and your one was better for longer, then starts going down hill.

[burgers22]

Its fine for a while, and your one was better for longer, then starts going down hill.

That's odd, do you think it could be anything to do with fuel trims? Mines been fine on the MAF setup.

[Benny]

Unsure.

I copied my maps over from 90550001 using the BIGMAP translator spreadsheet, threw them in and away we went.
I'm re-mapping my fueling again in the next week or so with LS off, i'll then export the fuel map into yours again and try once more, i'll also compare the idle tables a little closer too!

[Icem@n]

i cannot edit the ROM in ecuflash v1.43 it just reaches the boost tables and it just gives and error. Any ready why that happens or how i can fix or work around it?

[burgers22]

What version are you using? I tried the latest beta, 1.43.3120 in Windows 7 and it crashed all the time. 1.43.3000 works fine.

[sbn1979]

Work on a 8 marcel ?

[burgers22]

I'd guess it would work on a 260 as it is. I think this ROM has been made to work on an MR, give it a try, nothing to lose except an hour or so testing. You may have to mess about with the immobiliser codes, but there are only so many variations there.

[GrayW]

It does indeed work on JDM VIII's. If you are running a 3 port on an MR, you have make sure it's connected to the primary solenoid, or if the OEM boost control is still in place you will loose control of one of the solenoids. SAS functionality is also excluded from the ROM.

[Icem@n]

I will try the 1.43.3000 cause i was using the 1.43.3120 and see what happens. I want to try the 9653 v7 on my e4 to see how it behaves. All i have to do is use the bigmap translator and move fuel, ign, injector? I was also reading that ppl get high idle cold start but since here in Grenada its not that cold i hope i will not have the problem but if i do does anyone have a work around for that?

[Icem@n]

Yep it works fine. Thanks much man so i will be off to testing v7 on my car while i wait for 9055 v7.

[And]

to make the v7 xml work with the newer ecuflashes do this and it'll work, find the line

<table name="== EDIT THE TABLES BELOW FOR LOAD OR PSI BOOST TARGETING ==" category="Global Boost Control 'TYPE' (Choose LOAD or PSI Targeted Boost Control)" address="0" type="1D"/>

just delete the address="0" part from it, save and then all should be ok

Tried that bro and same thing happen it crashes and ecuflash closes off

[And]

have you added anything to the original xml? can you send me it and I'll find out where your problem is

[Icem@n]

Got an e-mail to test it and replied. Waiting for Tephra to respond.

Any response yet from tephra 9055 v7? I tried the 96530706 v7 on my e7 ecu it started good idle was a lil rough, took it for a drive but when i stop at a light the car dies with me over and over. How can i resolve this idle issue?

[todd]

Any response yet from tephra 9055 v7?

dont hold your breathe on that one :rolleyes:

[Icem@n]

ok well if it looks like the 9055 v7 will never be out anytime soon has there been anyone out there that got the 9653 v7 to idle properly on the e7 ecu?

[cammy]

I just loaded v7 96530706 on my 7 idle was a little rough to begin with, but adjusted the SAS and seems fine now. So far so good with this rom. :smile:

But I am running in a new engine, so not running any boost and the fuel map is a bit sloppy so, will see how it goes when it comes time to tune for power.

[Icem@n]

What changes you made to the SAS and where? Is it possible for you to give me some assistance to sort mine out?

[neilm]

you need to park the sas in evoscan then adjust the sas screw on the t /body till then un park it and see were it idles adjust if needed

[burnzy]

9653 works fine on my car, the reason you might be having problems is that the injector voltage latencies are different, copy the 9055 values in, also the maf scaling is different too so copy that as well and you should be fine, i've ran 9653 on alot of e7 ecus without probs

[tscompusa]

It works pretty good guys. I tuned quite a few 7's on v7 roms and they all seem to handle it pretty well. I like v7, because it logs so much more data then the old roms since theres so much more map resolution.

If anyone needs any specific information just ask, and i will try to answer the best i can.

[burgers22]

Good to hear you guys are doing OK on this ROM. The file I uploaded was from my own car, so was just a base tune for a stage 1 engine, with some timing taken out to keep things safer for new users.

[ecktt]

I wanna try this rom again. Is there anything special to be done to minimise or eliminate idle problems and throttle hang?

[kelvin]

Is there xml to go with this? When I try and load this in ecuflash it crashes.

[And]

this issue has been solve with the v7's xmls you just need to do a search

[w2j]

finally tried on my car tonight uploaded rescaled injectors ect. Started right up however it went super rich on the wideband using the same values from 90550001 from my 14.7-14.9 at idle it went to 10.5afr did not bother to drive it seeing it was so rich on startup. Don't know if the def I have but Injector Battery Voltage Latency Compensation is under "Global Fuel Settings" and Injector Size Scaling is under "Main Map Fuel Settings" is anybody else having this problem?

Loaded it up Saturday. Getting some strange LTFT issues. Also ported my 90550001 v5 settings across. This ROM seems to want a lower injector scaling and less latency. The LTFT (any) will change once or twice and then stick. Its was pain pulling aside and resting the trim from the battery pole. Getting some lean spikes and the sometimes it feels like its staling from a prolonged drive into a idle cruise (parking lot). The cold temperature injector primer need a lot of work as well for the Trini climate

[w2j]

bump for help

[burgers22]

The ROM does start up quite rich, typically low 11s on my car. I've not really found out why, but after a 5 mins or so it settles to 14.7 What injectors are you using? Remember, I didn't do anything more to this ROM than set it up to give no CELs and be pretty safe on a stock car, I guess the climate in the west of England will be a little different from W.I. ;)

[w2j]

^ I will reload this weekend and give it another try and let you know bro.

[Icem@n]

I give up on the 9653 v7 for the E7 ecu, just will have to wait till the 9055 v7 comes out whenever that is.

[burgers22]

Shame it didn't work for you Icem@n. The idle can be one of the most frustrating things to get right. Did you change the ISVC settings much?

[Icem@n]

Yea i played around with it for Hrs but didnt make any head way at all. Seems like tephra gave up on us with the v7 for our ROM. lol.

[burgers22]

Do you have any logs for your car at idle? If you want I'll take a look and if you mail me the ROM I'll see if there's anything thta I can do. Can promise anything but I'm intrigued as to why some people have issues I don't. A breif spec of the car would be handy, BOV, SAS, EGR that sort of thing. Please make the ROM a .bin file if you mail it to me.

marcel.barclay@gmail.com

[Icem@n]

do you use google talk? E-mail sent let me know what you think. Oh and don't forget that in the caribbean our weather here is in the high 70s early 80s Degrees F. So its much warmer that the UK.

[ecktt]

Keep us posted onthe solution.
btw...I would not give up on Tephra just yet.
;)

[RJSP]

Hi guys, will this rom work in a Euro spec (German I guess, not UK) Evo VII? A friend just bought a mint VII sold by Mitsubishi in Peru, I still have to read the original ROM to get more info.

Thanks,

Ricardo

[todd]

should do theres a v7 90550001 available now anyway

[burgers22]

90550701 is the V7 version for Tephra mods, he has asked that people donate to be able to use this, which I thinks is fine. there is a minor problem in that the ROM causes the WGDC to add 5.5% to the value you enter, but I've done a quick tweak to the xml to make both match. Find tephra at evolutionm.net and donate, he'll send you a ROM.

[amzevo7]

This works pretty well on my VII, no CELs and drives very nicely.

can u post up the xml files.... can test the car on my dyno and revert.... cool

[burgers22]

Here you go

[foxbat]

The car won't start after flashing this rom! The car is an E3 with a JDM E7 ecu, been using 90550001 v5.10 perfectly fine. Should I try 90550701 v7 instead?

I don't see why not. Its a pretty ROM with a bazillion options. I only wish there were more inputs on the E7 ecu to use NLTS, AFR Safety monitoring and alt map switching at the same time.

[foxbat]

I'm not sure why too! 90550001 v5.10 is currently running perfectly fine. Perhaps this V7 version (96530706) is not meant for a JDM ecu.

did you try swapping pins 8 and 22 ?? fuel pump

[And]

why don't you use the v7 of the 90550001 rom?

[foxbat]

did you try swapping pins 8 and 22 ?? fuel pump

No, pinouts are different between JDM & other ECUs?

[foxbat]

why don't you use the v7 of the 90550001 rom?

I think it's called 90550701 v7...correct?

[neilm]

I think it's called 90550701 v7...correct?

yes thats it

[todd]

between some 9653 is an e8 rom

[todd]

I think it's called 90550701 v7...correct?

nope its 90550001 v7 or 90550701 :lol::lol:
