While getting ready this morning I realized something about my previous E-Manage NA tests on a TL-S. While it was not able to directly advance the timing due to a lack of a real crank reference or just a single coil signal; it should be able to indirectly advance timing.

Considering that most cars advance the timing when lower loads are calculated. It would stand to reason that by reducing the primary air flow signal enough could give extra timing. The needed fuel would the be added back in by directly extending the pulse width.

This is just a thought but one I will certainly be testing soon. But this is something I should have tested before. :o

 

thats along the lines of what i used to ask you...though didnt know how to word it...but trick sensors into making the ECU add timing...

 

So it cant "really" advance timing. I remember a while back when you did a test with a voltage meter and said advancing the timing was able.

Is there another alternative other than fooling the sensor?

 

The timing advance appeared to work when viewed on the scope. But when put in the car things changed and it was setting the CEL for misfire codes. Plus, power was way down due to the codes being set. The problem was that it was not ‘guessing’ very well at what the timing should be.

The problem is that it doesn't have a crank position reference to coordinate with the six individual signals. Had this been a single coil system it would work as there is a single signal to reference and timing can be determined easier.

However, I believe there is a way to get more timing in a round about manner. I plan on testing this soon too. By decreasing the MAP sensor value at WOT the ECU will calculate a lower load value and should run more timing. To offset the lean issue which would occur, you can extend the pulse with to get the A/F numbers where they should be. This is obviously hypothetical but has some ground to stand on; it just needs to be tested.

 

I just hope someone will help you out and donate their car to a good cause..

In the meantime, we'll keep working on the UniChip and see if we can't come up with anything better..

 

steve

i am gonna run the e-manage if the uni-chip doesnt work for me, it is possible to run it n/a with the right tuner

 

A possibility per my current hypothesis but it wouldn't be the base E-Manage or the full system either. That guy you spoke to is an idiot for making broad claims without experience on the application. Anyway, it may be able to make a little power but I don't expect much. But it is worth trying just to see the results. Remember, I did see gains but only on the order or 2 - 3 WHP. The TL-S was making nearly 232 WHP with the basics.

The E-Manage main unit plus the required harnesses runs nearly $400 and that does not include the 28 wires installed nor the software. It would take about 2 - 3 hours to install it correctly and would not be PnP. The price for the PnP harness is available.

 

so u think i can get better gains from the uni-chip??

 

I know of a couple I can use. I plan on testing the RES plate along with E-Manage during the dyno session.

 

Nope!!!

The E-Manage has no direct way to control timing advance which is critical to gaining power. The is the benefit of the Unichip.

 

Now that's interesting . . . .

I've got cash stashed for RES already, only challenge will be get some for the e-manage set up . . . I might need to got to Vegas or buy a lotto ticket . . . or something. :P

Don't worry . . . I won't be using the RES funds . . .

So you think the UniChip is the best alternative just a more expensive one..?!?

I like the emanage b/c it would allow more control and adjustments for newer mods rather then sending the chip back and/or going to a dealer each time..

 

Yep, and it all revolves around the direct control of timing.

We'll see what we can get out of it though.

 

How much longer til the RES dyno?

 

A few weeks.

 

Can't wait to read the results . . . I got my fingers crossed for the test

Is this the same res plate that you made a long while ago? It was like an inch thick that sat ontop of the engine?

 

i just went to a shop called ptuning the do most of there biz threw there web site www.ptuning.com and they siad for my car they would defentily recomend the emange over and stand only system because it is a piggy back. and scalbert what is the RES???

 

Yes and no. It is the original one but with some modifications.

 

Both the Unichip and E-Manage are piggy back units.

The RES plate is a device intended to enhance the resonance effect in the manifold which may increase power.

 

g/l with the res steve. i hope it works out
