E- Manage and Maft?

[thedsmsource]

Has anyone ran a greddy emanage along with a maft? About ready to try this and wanted to get some feedback.

I have not, but there's no reason you couldn't.

no reason it wouldn't work. But... i was just reading this....kind of interesting. Every car is dif. however

ok, link doesn't work and i am not computer savy enough to figure it out. sorry. The dude had Emanage and MAFT and couldn't get the car to go past 4200. Frustrated, he un hooked the Emanage and made a dyno pull w/ just the MAFT. it was much better, 469whp better with a 462whp the very next pull. I don't know why i felt this better anwered your question, but i do think I wish my GVR4 made power like that with only the MAFT.

Works great for me.

Emanage is on its way, I cant get the car to idle very well with 880s and the maft. Timing is also too high for my liking as it knocks like a mofo at part throttle and in the higher rpm range,from what I can see, too much timing.. Hopefully the emanage will get it better for daily driving. The emanage should take car of this, and then some.

880s are honestly to big for a piggyback, however the e-manage should be able to help since you will be able to get timing under control with it. i would recommend getting a EPROM ECU and a chip for your injector size

Anyone who doubts the MAFT, check out that thead. 469 whp at 25 psi on a 3055. Very good.

Are you suggesting not to run 880's with the emanage even though the emanage has an injector correction setting? I have yet to really mess with the e-manage, but if this is a problem, I would like to know now. I was planning on running 880's with my FP3052, so this is why I ask...

the injector compensation works the same way as leaning out the MAF readings does. the function on the software is jsut there to make it easier to set up a baseline. you'd be leaning them out almost 50% which will give some pretty rediculous timing advance

 

[markgholland]

So, correct me if I'm wrong, but in order to actually start at the tuning process theoretically with the stock settings, I would have to compensate it with the e-Manage, and get a www.dsmchips.com chip that compensates for the larger injectors?

This is where the emanage is good, it can control ignition timing so you can compensate for the extra timing. It would be nice if the injector compensation did this automatically. You have to buy the ignition harness and do it seperatly.

Actually, kinda sorta.

The emanage will compensate the same way an afc does, if it is without the injector harness. It will lie to the ecu telling it, hey 1400hz of air are coming in, go right ahead and advance timing through the roof. You also only get 50% "fuel" adjustment

Now with the injector harness, the emanage will tell the ecu, "ya you're still running the 450s, so keep the stock timing map in the picture". This is even with 650s,880s etc., The next problem, in a way, is that you will hit fuel cut if your're running more than around 17psi....this is where the emanage comes in nicely..it can "clamp" the air flow value at say 1600hz so the ecu never sees anything more than that so you will steer clear of fuel cut. Yet the mas airflow sensor will read up to 2500hz+(gm mas in my case), and I can tune off of knock with a logger, and add fuel with the emanage maps +-100%

The emanage acts like an msd ignition in a way but it doesnt amplify, it reduces the signal. It takes in the stock injector pulse(say 450s in our case), tones it down to whatever size(880s in my case) without any timing advance, funny acceleration, etc., It reads duty cycle and will warn you when you're in the 90% range.

Now, if your mas air flow sensor is being overrun, you can clamp the hz value before fuel cut, or near the overrun issue, and use their map sensor to tune with. I will let you guys know how it idles when it gets here...so far the idle really isnt that bad with just the GM maf-t, but occasionally it will stall when im coming to a stop...

which is another feature of the emanage that is a plus, the anti stall...I know its becuase of the 880s because it wasnt doing it with the 650s.

The ignition harness is also a nice way to keep things under controll, if your running nitrous, you might want a couple degrees pulled out on top.

But keep in mind, all these features you have controll over are very sensitive. One wrong move and BAM! blown motor. So baby steps at a time guys, I hope I dont end up kickin my ass over this line.

All the features explained can only be accessed with the support tool. The injector harness is highly recommended for any upgraded injectors as it keeps things "safer".

Lets keep facts on here please, no offense or anything.

I think this link was posted in another emanage thread, but there is alot of info at the bottom of the page.http://www.mohdparts.com/emanage/

Well well well, wtf was that?!?! see what happens when I read instructions and listen to shops?

Unfortunatly, the emanage will not reduce injector pulse width, it will only INCREASE it. It does it at predetermined Hz counts(which you can enter). I have had better success tunning by zeroing out the MAFT as if I was running stock 450s, and let the emanage trim the map for 880s(I also had better luck setting it for 830s,fuel trims were happier). Idle is also smooth, much better than just the MAFT. I purchased the additional injector harness because they were out of the timing harnesses. I set my base timing at 5*BTDC and It is running strong. I am very impressed with the precision tunning that you can do with the emanage. Install was very easy, tunning is a little tougher than with just the MAFT. Ill admit, I cheated with the maft to make changes on the fly, then I go to the emanage and richen up or lean out whatever is needed.

Im am in no way putting down the Maf-T, that thing is awesome. Along with the emanage, they both make an awesome combo. I will still be getting the timing harness cause there is a tip in timing issue that I dont like. It is slight, but I know its there and it is annoying when I punch it.

-These are the VPC/GCC combo of the 21st century, but with sugar on top

I apologize about any confusion I may have caused, better late than never right?

I am interested in the Emanage. I currently have the MAFT and an SAFC (AFC is zero'd out for now) and I would like a way to control timing. I am afraid of a stand alone because the price and I am afraid I will not be able to tune effectively with it. I dont want to have to pay someone to tune my car and also have to pay for multiple hours on a dyno.
With that in mind I would like to see if the Emanage will be a viable alternative for me. I am trying to build a low 10sec car with 500+whp on boost alone. I have a 3065, 850cc's, built motor, soon to have 272's, and the list goes on. A friend of mine (with no DSM experience) has been telling me that no matter what I get the stock ECU will be holding me back because it cannot operate fast enough. I dont know if this is true or not and I am anxious to find out. How fast can the stock ECU go with the aid of piggyback equipment?

Thanks
I hope this is considered relative to the thread.

Does Anyone with a 2gen have and Emanage...With 720cc...or even 660cc injectors..
