Single with out proper mapping?


Pig

Recommended Posts

Ok i am getting my car back on sat.

 

I have gone with E manage ultimate but cant get it mapped (other than a blueprint) for a month or so. have an AEM wideband so can see if i have enough fuel. Will i be ok to run it? Also can i boot it ?

Cheers

There is a very rough map on my site for a e-manage blue for a UK spec running 550's on a T61 at 1.3bar. You may be able to use this for the ultimate. It is far from perfect is fuel only and very rich but should be safe..

 

Note that injectors are running at ~90% at WOT.

 

DO NOT BOOT IT WITHOUT MAPPING IT.

I don't know what fueling is on the std ECU so it will be an educated guess,

just make sure you are seeing 14.7 (you won't have a choice in closed loop mode) not sure where this mode stops on the Supra, but on my S14 its about 3,50RPM or 0 PSI, the to be safe, aim for a progressively richer AFR, as you come on boost/load as long as you are seeing 11.5 AFR by 10PSI and possibly 11.AFR by 15PSI you should be fairly safe, just be careful and keep an eye on the AFR and listen for any det, be able to tell you more once i find a good Supra to play with;)

Sorry i presumed that you would map it yourself? if not then forget my last post, and go with johnk s advice!

Just keep off boost til it is mapped

 

but its going to be ages! Cant be doing with that. Unless i go somewhere else for mapping but ian c is the man for mapping so dont really want to.

 

Btw,

 

Uk spec 550 injectors, t61 std IC

Dont run it until properly mapped m8...

 

Stick an FConS on it (min) - get it up to Owens and get it mapped - sell the Ultimate (please someone tell me that it will ever work...) and enjoy your car...

 

Oi - mine bloody works :tongue:

 

OK, the MAF is new ground for the EMU but I spoke to Matt H earlier today (who is sorting out the wiring up for Pig) and I emailed him something tasty to try and sort this out.

 

I just can't do much for a couple of weeks but once I can I'll get stuck in.

I have, yes. It's on a MAP-based J-spec. There are some functions of it I haven't looked at yet so I can't say if they work or not but I've already got it a) doing all the blue could do, b) running my car better, and c) upped the rev limit :devil: mmm, 157mph in 5th hahaha

 

It's a good unit but it's kinda new, believe me when I say there aren't many people in the world who know how the damn thing works at the moment!

Yeah i have already tried one on my S14, but i had a misfire that i couldn't get rid of, something to do with the timing map, but it would still do it even if no adjustments where made, so i got fed up in the end and sent it back to the supplier, Greddy where next to useless:rolleyes: i have my old trusty blue emanage ready to go on my Supra when i find one, but i still fancy an ultimate as they are the next best thing to stand alone at a fraction of the price:) if they work fully;)

Ian - I stand humbly corrected (I was not aware that it is up and going)

 

But you are just one very busy bloke - and who else is going to map it for him...??

:rolleyes: :taped:

 

Jon you've been without the car for a bit and so I'd say just keeping a lid on things for a month is possible. If not then don't drive it full stop.

 

Don't know which map you've got for it, but if it's a translated map from a blue for the same spec of setup as yours then it should be fairly close...

 

TEST AT YOUR OWN RISK...but if you want to keep an eye on your afr's and test it then this guide should help.

 

AFR's should be based on boost....the boost will indicate load. Anything over 0.6bar should be at 11.7:1. IMO off boost should 14.7:1 - 13.7:1 and the closed loop should take care of this anyway in most situations. Between 0psi and 10psi the engine should see the afr's go from 14.3:1 to 11.7:1 obviously getting richer as it gets more boost/engine speed.

 

Idle and cruise should be 14.7:1 Though some engines are happier with other idles such as 13.7:1 and 15.7:1 I've seen both on Supra's.

Ian's the only guy in the (english speaking) world at the moment. As he learns more others will learn - Jon's had to invest heavily due to various issue's. Just telling him to ditch all previous efforts and do X isn't going to help. Patience is what's needed - he's shown plenty so far.

I have sent Ian a draft XL sheet that was based on previous MAP Vs MAF voltages. Ian is a smart cookie and it wont take him long to get his head around the whole MAF delete thing.

Great stuff! Seems i have got the answers i expected. Thanks alex for the info i can test with. I think i will ask terry to check it for me when setting it up. However, will just hold back and not boot it :( lol.

Iain, thanks for replying to this: Will be hanging around for as long as is necessary :respekt:

 

Thanks everyone!

Heh thanks for the kind words folks :)

 

I've sent Matt H an engine.dat file that has a UK spec 2JZ hacked into it, hopefully that will work with the MAF in place. If not then we'll use the MAF->MAP feature instead, plumbing the stock MAP sensor into the E-Manage and spitting the airflow output map results to the stock ECU. Simple ;)
