This is for Serge's car (02AV6). I added the new additional harness to his PnP harness along with making the needed alterations. Below is a list of the changes/additions made to the harness:

Change of TPS tap to using the additional Analog Input and Analog Output. This should be able to be used to create a faster throttle response possible to help with the Automatic shifts.

ECT and IAT being read by the E-Manage. These could be used to trigger relays to turn on fans, etc. when temps are exceeded. Or timing and/or fueling adjustments can be made based on these temps.

Crank angle now used for the RPM input. This should allow the E-Manage to know exactly where the engine is at in a revolution. This should now allow it to advance timing which will be beneficial for NA applications. It also allows you to see the factory absolute timing as well which helps for tuning on both NA and FI applications.

Instead of having the injector signals tapped, they are now intercepted. Meaning, the E-Manage is in complete control of them just like the ignition signals. This will allow for direct, not indirect (indirect is by way of altering air flow signals to the ECU), control of the injectors; you can directly reduce pulse width as well as increase it from the factory base. Larger injectors should be much easier to tune for now.

The E-Manage is tapped into the Counter Shaft Speed Sensor which should allow the E-Manage to monitor speed. This is good for logging reference during tuning, but can be used to alter fuel and ignition values based on speed.

Besides the above, the one other new option which could be used is the A/F Input Harness. This, when applied, could make tuning very easy.

The new interface is great but it does have quit a bit more to it. The new features are great but may be a bit cumbersome at first. It will take time to get through all of it and learn the best way to tune for the J-Series. In the end we should be able to develop a base of programs for various tunes and hopefully share them. I do wish Serge was a bit closer as I would have loved to have played with it on a vehicle, not just on a test bench.

 

Outstanding-

What's your take on the rev-limiter? Is there a difference between the auto harness VS. the 6spd? Are you ready to have me send you one?

 

The rev limiter will be tricky and we need to be sure it is reading the crank signal fine. I would wait on trying the revlimiter feature until everything else is tested and verified. But it is still a possibility.

And yes, the 6MT harness is different. But still simple. Just different pin-outs and connectors.

Let me see how Serge's works and if any other changes are needed and then we can begin changing/building others.

 

totally cool.

I wonder if it is beneficial for me to upgrade to the Ultimate. I have to send my harness back to you this winter for repairs anyways..

 

Once we see what occurs with Serge we can see the actual benefit. But IMO, unless bigger injectors are run, the blue unit might suffice for FI application.

I think the real benefits may be to the NA crowd.

 

Great can't wait, yep wish I was closer. Will hook it up this weekend to read/record REAL TIME and take it for a spin

BTW, my Vortech SFMU (CT FPR replacement) should see no more than 80psi FP at WOT with smaller installed cal. disk, but I will be carefull, not going at full boost yet until completely tune (scheduled next week). It is rising rate, I forget what values still adjust FP great and current idle reads as 35psi with 360cc S2K injectors.

Ok, so separate NEP (RPM signal) not needed since now it's tapped into included connector A, correct? Just calibrate TPS and is boost cut set to 2.7V same as on blue unit? Also, did you upgrade the software to v1.6? I'm going to install the orginal installation disk then to upgrade to 1.6, and seems firmware has been upgraded.

As far as ignition timing, I'd like to advance before 3500rpm for now where it lacks most. Do you think single degree is fine to start with? Will stay away from the accel or decal parameters until later and let you know if EU reads IAT/ECT signals.


Thanks Steve

 

this is gonna be great. I can't wait to see the oucome of the timing advance with this.

 

You can hook up the NEP signal just in case the CPK is not being read correctly. There is a setting telling the EU which input it derives RPM from. If it is not reading correctly, you can change it to use the NEP signal.

Boost cut is set at 2.7 VDC.

Yep, v1.6 is loaded on the unit. To see the version just click on Help.

Yes, start with 1 degree and move up from there.

Have fun....

 

Will do

 

BTW was checking new Bosch pump and it was too hot touch (the motor). Is it normal?

 

Not too surprising. Just keep an eye on it.

 

Wow. Looks like you're going to be having some fun. Hopefully I'll be next to play with this. Thank goodness I'm like 30 minutes away from Scalberto.

 

Lucky guy

 

30 minutes, how slow do you drive. I can be in downtown Alpharetta in less than 15 minutes on a good day.

 

Sounds good Steve. Hopefully everything works out. I'll be picking one up in the next few months.

 

Know where the North Georgia Premium Outlet mall is? I live about 5-10 minutes from there.....

 

Shoot, that is up by Dawsonville I beleive. Or at least just north of Cumming. That is a decent jaunt.

 

@ Cumming , GA

Steve what would I need to send you for a PnP harness? Just the $99 harness?

 

When the 400 ends, it becomes SR 400. It does that at the first traffice light. I live at that first light.

 

I did the same thing the first 5 years I heard it.

 

i should of stayed at ft. stewart

 

Another thing I was thinking about. Does the EU have an input for a 0-5v analog source... like my AEM wideband? Could be useful for datalogging if it does.

 

 

Nice features mang , I heard from VQ guys (while different vehicle) that although the EU takes a crank angle signal, for complete timing control, it doesnt actually intercept it...so there is no way to trick the ECU into thinking the engine is reving at a different speed. I really wish J-series can advance timing. I guess will see Serge's report

 

I guess I didn't phrase my question correctly. Will it display that as "v" or as AFR?

 

I'm sure you can have it display the AFR, since it advertises connection to your favorite wideband sensor, in addition to being able to auto adjust fuel maps to keep AF ratio at preset value. saves a crapload of tuning time.

 

yes, but from what i gather, it will not fine tune every single point on the map, its more of a broader rpm range tuning. and it doesnt do this continuously, its only while setting up a map. also, there needs to be an external channel output from the wideband for this to work. it does save alot of tuning time though, but that hasnt been tested to see if it works well or not.

 

How are you so sure? All signals are 0-5v yet some widebands read different ranges. i.e., AEM reads <11:1 - 16.5:1 whereas the PLX reads between 10:1 - 18:1.

At 5v the AEM will read LEAN as will the PLX... BUT the actual AFR isn't the same because the AEM doesn't have as wide of a range as the PLX.

 

You can adjust the range as needed so the engineering units work out.

 

True, it is not an absolute but should aid in getting some of it within range. You could err of the rich side and then take it through and let it adjust. At a minimum, having the log of A/F ratio versus RPM and speed would be nice.

 

Nice work Steve!! Great to hear Greddy has updated a good product... making it even better!!

 

Nice

 

I'm so sure because making such a great product like that and leaving out something so obvious as calibration to different types of O2 sensors would be moronic.

I was right.

 

Steve, did you set the engine code in parameters settings? Picking up tonight, just wanted to know before hand while reading the manual .

 

Yes, but it is not so needed. It justpre-sets some basic parameters which you could set on your own. Nothing major was changed and both the J30 and J35 selection had the same information except for engine size which is not needed in most cases.

 

datalogging is a very nice feature. if i could afford it, i would upgrade to the newer unit for its new benefits. steve, can we raise redline with the ultimate? i remember we discussed it a long time ago and the verdict was that there wouldnt be any benefits. however, when i look at my dyno graphs, i actually make stronger or at least near-peak power right towards redline. im not saying it will make more power with over 7k revs for sure, but i doubt it will drop off either! finally, how safe would it be for us boosted j32's to raise it?
allmotor, any idea on this?

 

 

Torque already begins to fall off pretty steep at 6400 rpm... doubtful you'd see anything worthwhile by raising the rev limiter a few hundred RPM... say 7500.

 

thats what i was thinking, but we wont know till we try. if it can keep the power curve flat, it would be nice!
for example, if i were to boost up to 8 psi, that would mean i would have to shift to 4th right before the 1/4 mile mark. with a raised redline, i can take 3rd a few hundred rpms higher and pull off 1) Better E.T. 2) Higher MPH
now is it safe to do so and can it be done is the question

 

So far I disappointed, we'll see if Garage Kwai can figure out the solution (dropped it off).

TPS calibration has failed with engine OFF. According to manual some cars might need to be running to do the throttle calibration which is odd to me. So I did that, and looks like it worked, however when fired up the car, the idle was very rough.

Placed in neutral, gave a quick stab on the throttle, it did change values, but hesitated to floor it. Very rough idle and once foot removed the car "died".
Another observation, data logging didn't show crank signal values. I changed to RPM signal, connected wire and it displayed fine, however the car still idles very rough and after very short time the car dies again.

So, I removed EU harness, double checked if car runs fine on stock ECU with no issues, and dropped it off Monday night at the shop. Need to test fit a single exhaust conversion anyway, plus hope tuner going to figure out EU this week.
