OFT tuning with other turbo kits
 

I know OFT can be used to tune the SBD kit but what about other kits. For example if i ordered a Fullblown or JDL kit can i use the OFT to tune the kits? If not do i only have the choice of using Ecutek? :iono:

It theoreticly possible to tune those kits with oft but you would have to do it yourself or get a tuner to do it.

most tuners will probably baulk as they cannot lock their tune from copying and they are not faliliar with oft and the patches to ecu firmware required.

so your probably need to get car to shiv.

shiv now has overboost cut patch and soon flex fuel.

which pretty well means Ecutek

Shiv can normally do personalized tunes or can adjust your tune and send a map for you if you send him your current tune map. It's easier for me because Shiv and I live in the same town. Send him a PM asking him what he can do, I also believe he just created a thread today or yesterday about him branching out to other FI kits.

Heres the thread: http://www.ft86club.com/forums/showthread.php?t=100974

As long as you are happy tuning yourself, or have a tuner who is happy using RomRaider, you can use OFT or Tactrix.

I've tuned my Greddy kit with RomRaider and Tactrix - can send you my ROM (based on A01G) for an idea of how it runs.

Hi ztan,


I have the Phantom ESC. There is an OFT tune available for N.America. After repeated requests from Shiv, he sent me a petrol and E85 tune.


I have loaded the E85 tune. The tune has problems. Are you interested to look at them? I have A01G ROM. Shiv has not replied to my feedback.


E85 tune. The cold start idle goes very rich, low rpm, shaking, stalling. I have a attached a log of this. The long story is that I asked someone to copy the N.America tune to the A01G rom. Similar low, stalling idle problem. It was thought to be due to the Australian rom definition had missing tables. That person fixed the idle issue. He said the problem was in the cat warm up tables. However that tune was too lean in the lower rpm and full throttle and we gave up and I'm not using that tune.


Also, Shiv's tune, at low rpms, around 2k rpm, typical for cruising and overtaking, any boost makes it very rich and severe bogging, the car slows down. I have attached a full throttle log for this. During the full throttle log, the car is able to accelerate past the bogging. However with normal driving overtaking in higher gear and mid throttle, the car bogs and slows down (Only full throttle log attached)

assuming the tune you posted is shivs tune ?

if so fixed a few thing in start and load limits

Yes, is Shiv's tune.
Thanks a lot, I'll try the new tune over the weekend and check the logs.

keep us posted

if it still plays up

Disconect poer to the ESC so it wont apply boost
Load a standard oft stage 2 e85 tune into car

If it still plays up with standard e85 tune and no esc boost then its likey a hardware problem with car like intake or exhaust leak or dirty or crook maf sensor ect.

I bet the person's name starts with R, and ends with "obert".

Should be easy to copy over the relevant tables from C to G.

Yes, Robert tried to help, but the tune was too lean in low revs and we gave up.


If it is easy, why is Shiv's tune bad as well?

Hi mate,
Nothing too obvious in the ROM.
1. In your log, you are getting load values of 2.5 early on - does this coincide with ESC activation? You're A01G so I'm assuming manual and no torque converter to mess up load transiently.
2. Have you checked your EVAP hoses under the manifold, they pop real easy and if they have not been clamped, you could be leaking boost (though this would get even worse at high RPM which you do not seem to be getting).
3. Worth rescaling your Front O2 sensor so it reads a bit more accurately - yours is currently bounded low at 11.32:
http://www.ft86club.com/forums/showthread.php?t=82875 see last post for best scale I have come up with.
4. If no boost leak and you're still running very rich at low RPM when your ESC kicks in, you'll either need to rescale MAF properly to suit your own setup, or play around with EL comp table.
5. There is a tendency for Subaru ECUs to go rich on CL/OL transition - look at the NASIOC forums searching for "rich dip". Most people accept their numbers going off as long as the car doesn't bog. Can you log CL/OL status?

I have attached logs

Cold start stalling, very rich
2 full throttle with boost pulls, lean at around 2-2.5k rpm
1 pull with ESC switched off
1 pull with Stage2 EL E85 with ESC switched off. ------- seems to be OK. I guess the hardware is OK.

--------------------Yes, look at the boost channel, boost coming on. Yes manual-----------------

-------------------I have clamped both ends of the tube. It made no difference -----------

------------------Thanks, I try and work thru this------------

------------------OK, rescale MAF. What is EL comp table?

-------------I can log Closed loop/Open loop status------

Does it stall\run rich on cold start with standard stage 2 EL e85 tune ie non esc ?

No. All other tunes OK. Just occurs with this tune from Shiv and a tune I had converted from USA to A01G

Hhmmm i have had that once before not sure if its a weird tune corruption or something.

might be best to start with a stage 2 el e85 tune and apply the esc mods to that

i think theirs somthing a miss with the base rom

Funny how you say "which pretty much means Ecutek", yet all of the problems described in this thread I've never seen with Ecutek. Load up a base rom, apply RaceROM, good to go. Sorry, you must have forgotten electronic boost control capabilities and all of the available custom maps. Must've also forgotten about how easy it is to datalog, review logs within the same software, then flash, all without ever leaving Ecutek. The only thing it lacks at this point is live tuning. Live tracing is meh.

Not all tuners lock their tunes. Plenty of shops out there will send you the final ROM, just ask. If they say no, take your business elsewhere. I get the hate on locked tunes, but lets be real. "Locked tunes" is the only argument anyone on this forum ever has against Ecutek. Reputable shops will provide the ROMs for you unlocked.

Anyway, sorry for getting off-topic. Just found that comment quite amusing.

I think that was a typo should have been getting closer to ecutek :-) , but anyway

I have ecutek as well, unfortunatly in my country all ecutek tuners lock tunes, im not sure elsewhere buy very few tuners on any tuning platform will sell you an unlocked tune you can edit yourself, as it means their work can be coppied.

Pretty hard to beat oft on datalogging just plug it in, no laptop required and the tuning alerts are also extremly useful. ( not even ecutek has those)

Tactrix is good as well

Each system has its good points and shortcommings be that functionallity price or ease of use liciencing locking ect.

Pick the one that suits your needs and run with that

Most problems with opensource stuff is because people are doing tuning or fitting parts themselves. Ie thay change someting in tune that has an undesirable effect or some other editing problem. Or they are fitting parts themselves and get air leaks or some other fitment problem

.

Whereas 99% of ecutek tunes are locked so all you can do is flash ( ive seen a few flash issues with ecutek as well and just last month to ecutek guys bricked ecu due bad obd connectors) same issues as opensource.

The main reason ecutek is not used much especially on NA cars in our country is price

Tune on a naturally aspirated BRZ\86 is about $1800 australian dollars and it locked and that no cable included in that price either. And they wont do e85\petrol switchable tune, thay will only do it with full flex fuel and your looking at arround $3000 with flex.

If you could provide a list of reputable ecutek tuners that wouls provide unlocked editable by end user tunes that would be good im sure a lot of people would be interested.

Jamesm was on this forum did at one point but he does not do remote tunes any more i believe, and he was the only ecutek guy im aware of that does unlocked tunes.

I understand your points. Yes it is more expensive, but cost should not be a concern when running aftermarket FI on a N/A factory car. If people are concerned with cost, they shouldn't be modding these vehicles this drastically. That being said, most Ecutek tunes are anywhere from $800 to $1200 tuned, good to go. That is about the rates you'll see from getting a dyno tune with also needing to buy the $300 license. That cost is significantly cheap in comparison to other platforms. I'll in over 5k for my "tune" when I switch to motec. Its expensive, and if people dont have the money to replace a blown motor after voiding their warranty, they shouldn't be messing with cheap tunes.

I had no issues finding two different shops here in DFW which would leave my Ecutek tune unlocked. However the plan is motec now so that doesn't apply, but still... All you have to do is ask. If they say no, take your business elsewhere. Simple as that.

Flashing features? I've had zero issues with over 200 flashes on my car with Ecutek, where I'd have frequent connection issues getting things to write without errors when using a tactrix cable. I haven't used OFT on my car so I can't comment how well it works, however the OBD pin issue can't really be blamed on either option. Both would fail if that connection is lost.

Ecutek does have a recovery mode if there is a connection error during a flash. Just re-flash a stock ROM to repair the ECU, then re-flash your custom tune. Good to go. Not sure if OFT has that, but Ecutek needs the credit where credit is due. It is currently much more refined.

Sounds like tuners are on every street corner onver there here not many and almost all lock tunes especially on e utek or brzexiAgree ecutek is more sorted but just like guy fitting thdir own turbos some like to do own tuning and write their own code in some cases to do so it all depends what you want. Everyone free to make their choice Their are some tuners here using brzedit with good results on turbo and SC cars ás well as ecutek. Ecutek is the easiest option for most as the work is already done.

All ststems seem to have a recovery reflah mode but none will save you 100% of the time..

I believe ecutek however is the only one you can ship your ecu to for a bench unbrick at this time

DFW, TX. We have a good amount of speed shops around here I'd say. :)

i think i need your greddy rom,can u send it to me? thanks.

Dropbox link sent.

thanks,i got it.

i love u，aha. By the way, how many bar with your T518 turbo?

Just chiming in...

OFT is not limited by the power platform you choose for the car, its limited by the tuner.

Shiv is the only person I know that actively tunes with OFT; I know their are a few members which have helped others out by helping supply or even fine tune existing tunes, but you will be hard pressed to find a shop that's willing to tune with it. I know because I've asked a handful of tuners, only one of them was willing to do it, at a pretty high expense simply due to the extra steps and time required.

Because of this I'm leaving my short love affair with OFT to move over to ECUTek. Shiv is a great guy, and I trust his tunes; but I think he's pushing the limits of the workload he has as this platform gains popularity and more affordable power options available

0.7 Bar with E85 and stock motor.

the ECU has a built in recover...
 

I've recovered a tactrix half flash... the ECU itself has a built in recover that allows you to then just reflash.


Since the tunes aren't locked there's no need for a special recover mode.
