What is the Greddy e-manage?

[mtam22]

I think the MAP sensor in my Supra can't read more than 1.3 bar.

Does anyone know if using the optional 3 bar MAP sensor with the e-manage can help the injectors to fire correctly beyond 1.3 bar? Or is the e-manage 3 bar MAP sensor good for controlling the wastegate/actuator only?

[trust200]

you need the emanage optional pressure sensor to boost above your map sensors 1.3bar recognition...

[mtam22]

Thanks. Sorry for being so pedantic but have you tried this or got this info from literature posted elsewhere? Reason I ask is a friend insisted the e-manage MAP sensor is used exclusively by e-manage to control wastegate. It'll still look to the factory MAP sensor for fuel control purpose. Doesn't make sense to me why the e-manage would want to deal with two MAP values hence my question.

[Dr_Drift]

The additional map sensor is for the fuel and ignition control, nothing to do with actuator/gate/

Just to rain on the parade, a few owners of S15's have experienced coil pack failures when installed with the ignition harness.

[Dr_Drift]

jtir - More information please?

Yes, I have also heard from EVO 8 owners in USA who have the same thing happen. It is either firmware related or wiring related.

I know of a few S15's that have had no problem.

Latest firmware revision is 1.3x

Also GReddy now have released harnesses for the emanage so there is no need to splice wires.

Honda's

Toyota's

There is one for nissans, but only for GTR's.

Sweet... cheers Ed...

here is some more options for various ignition systems.

Have fun

Was originally shopping for the s-afc but after reading this you have changed my mind.

what kind of power increase would ther be after installing the e-manage and would it improve fuel economy.

Only have cat back exhaust, pod filter and bov.Would i increase power more by doing the front pipe first?

[ed]

Here is a translation of the official release from Greddy Japan about the e-manage v1.36 firmware...

* * * E-manage Version 1.36 & * * ********************

The harness kit (ignition) or, at the time of car classification harness use, the occasion where the ignition key is turned to OFF, correcting the fact that it has the possibility the ignition coil breaking. As for being a possibility condition occurring,

1. When correction value of advanced angle is input into mass with respect to the left of ignition timing revision MAP,

2. After turning the ignition key to OFF, until ECU (e-manage) power source is cut off, the model whose time is long (mainly JZ system of the NISSAN car and the Toyota car)

3. When the ignition signal while outputting control stop rpm (550pm) being below, when these three conditions are piled up only, is. (The possibility of being piled up generally is thought. that quite it is little)

* When you make a mistake in the wiring order of the ignition signal, the ignition coil the damage dying will be adding processing.

cost too much! prefer powerfc

?? E-manage is definitely way cheaper than a powerfc with commander. Even with the commander, you can't do half as much tuning yourself with the powerfc than the e-manage.

I've played with the S-AFC for a year and cannot get it to control my larger injectors. I got the e-manage installed in three hours doing alll work myself. Tuning is a piece of cake with a laptop and I get a nice 14.5 A/F from idle to 4,000 and 12.5 from thereon to redline. Mid range and high end improved out of sight compared to the fuel rich setup before. The e-manage is definitely the best bang for the buck out there and way ahead of the S-AFC and powerfc if you like to do your own tuning.

[sil21jun]

But you are talking about spending 1k(550 for ECU, 400 for software and wiring loom) on a piggy back and 1.3k(with commander) with a standalone.

What makes you think a standalone is superior to piggyback? Well, it is not. With the e-manage you have full control over fuel (within 150% of original injector sizes) , timing advance/retardation, boost, and can datalog injector cycle etc. You can't even datalog with your powerfc let alone see the whole 16x16 fuel and ignition map. Don't think you can handle additional injectors with the powerfc either. With the powerfc, you need to go to an authorised dealer with the Apexi excel software to tune. With the e-manage, all you need is a laptop, a disc, and a wideband O2 to do what was hitherto, doable by a professional tuner only. Don't forget, with he powerfc, you have to factor in initial tuning costs and the recurring tuning costs everytime you do some major power upgrade.

If you must go standalone, the only logical and economical solution is the Haltech. You'd want to do that if (i) your existing harness is tired and old anyway and you want to renew all sensors, (ii) you want to get rid of those restrictive air flow sensors, (iii) you need datalogging on more than just rpm, throttle position, injector cycles etc that the e-manage offer, (iv) you want to run NOS, (v) you're running mega injectors that are more than 150% the original flow. None of this minds you, is acheivable with the so called standalone power fc.

[sil21jun]

Whatever suits you. But I haven't heard of any car using a piggy back to run under 10sec on a 1/4 mile before. Maybe you can educate me with your knowledge. Also in my POV, wideband 02 sensors cost 600USD.

Just for your info, I don't like power fc either and I am running on a fully standalone microtech LTx8. I guess power fc is so much more popular than other management is because 1. its standalone. 2. It's standalone. 3. It solves all the aircon problem many other standalone ecus are having difficulty with. 4. not a tuner I know in Brisbane knows much about tuning e-manage. The only reason I will go for e-manage is if I had a V-tec and maybe hk has too many vtec till you got so in love with it.

The Techedge wideband costs less than half that and it's an Aussie product. You may also be interested in reading about Julian Edgar's article on autospeed.com.au comparing the virtues of standalones vs. piggybacks.

Fact that you don't see any sub 10 sec car running e-manage is no proof that they aren't competent in achieving what they are designed to do -- that is, easily tunable by user and offer full authority over fuel and ignition. I've never seen a F1 McLaren doing sub 10sec run is no testimony that they can't. In any event, I thought what's being discussed here is a suitable ECU for everyday tuning and not extreme applications like 10sec. E-manage won't be the right tool for extreme applications like that as you'll be talking about injectors that are at least twice the flow of the originals. The e-manage can handle no more than 150% increase.

I don't dispute the usefulness of standalones. Horses for courses and there's no best computer to suit all application. To wit, the e-manage suits my Mkiv TT perfectly as I run 25% larger injectors and I'm keeping the factory turbos. Harness is fresh and the Jspec car already runs MAP sensor. It's the optimum solution for this application and I need no more.

The e-manage won't be the solution for my RX7 as the main harness is getting old and brittle and I need it replaced. Instead of paying ridiculous money for a factory harness, I'm getting a Haltech E6X to replace the whole system for about the price of a factory harness.

I need to get rid of the MAFs on my 32GTR as they are a big restriction on the TD05s so I'm planning on getting the Haltech E11 which can be run in a piggyback configuration to retain all factory electronic options and a MAP sensor to get rid of the MAFs.

And I only need a chip upgrade for my Escort Cosworth because Ahmed Bayjoo makes a rally tuned ECU/injectors/3bar MAP sensor package that provides a perfectly tuned 330hp with no additional wiring or fiddling around.

As you can see, specific situations require specific solution. My comment on the e-manage is a general statement assuming that you're just looking into squeezing a bit more performance from the open loop end of the ECU operation by raising your A/Fs from the low 10s to 12 or 13s. The e-manage is totally capable of acheiving and that's all that I'm saying.

Incidentally, can't see any reason why anyone needs the e-manage for VTECs and hope it doesn't disappoint you that I never owned one.

HKS drag cars use FCON V Pro which is hmm a 'half piggy back'?

It still retains the factory ECU.
