Did you blow by an S2K in your video? and what is where your dash should be?
Hey Colston,

Yes that was a S2000 but it was a designated passing zone so he was letting us pass. That said, slower cars (like S2K) are required to allow faster ones (like GZE AW11) to pass ;)

I ran this course uphill and set a good benchmark. There was a light sprinkle of rain at the end but road was dry, not a single car in my way with maybe 6 or 7 on-coming. This was on Sunday 3/13/16 at 3:00. (i met all the campers driving home) with a full tank of gas and a passenger. Bone stock N/A 88 MR2.

1. Configuring the e-Manage

The instructions that comes with the e-Manage left a lot to be desired. Some diagrams are very hard to read, others have missing data all together. One thing to note straightaway is that I am using the e-Manage Blue, which is an obsolete version now superseded by the e-Manage Ultimate. I don't have any experience with the Ultimate, but here are differences between the two from what I've gathered from research:

Advantages of the e-Manage Ultimate:
e-Manage Ultimatee-Manage Blue (what I've got)
Fully control injectors, both scaling and pulsewidthCan only add fuel
Two step RPM launch controlNo launch control
Can replace AFM with a single MAP sensorCannot work without factory airflow meter
Full ignition timing control via aftermarket crank sensorsCan retard timing on most, but only advance timing on some
Multiple inputs for optional devices (AFR, MAP, EGR, Knock)   Only one input for one optional device
Data logging without laptopRequires constant cable connection to datalog, and can only datalog for about five minutes at a time
Supported, free updates, tons of community helpNo longer supported, hard to find help
Can be purchased newYou'll most likely find it used with an unknown prior configuration
Modern software with good export capabilitySoftware was last updated in 2006. Only exports to a proprietary Greddy format (more on this later)
Uses a standard USB cableDoes not use a standard USB cable (more on this below)

Advantages of the e-Manage Blue:
e-Manage Bluee-Manage Ultimate
Costs lessCosts more
Compatible with the Greddy Profec E01! (Example video)       Not compatible

What they both can do:
e-Manage Ultimatee-Manage Blue
Extend Rev limitCan do this with additional external control module
Adjust AFM voltage      Adjust AFM voltage


I got my e-Manage Blue from Bill, and I LOVE IT. The best thing is that on the US 4A-GZE, the Blue can both retard AND advance ignition timing! Apparently this isn't the case for most engines so we are fortunate to have full ignition timing control.


Prelude:
Before I go ANY further, I must tell you that you will want to be able to connect a Laptop/computer to your e-Manage the moment you get it installed. The reason is because as the Blue unit is discontinued, it's highly unlikely you'll find a unit with out any modifications pre-programmed to it. What if it is set for 50% more airflow at an idle? It might not even start up despite being wired correctly. And now I must share with you a very annoying feature of the eM Blue: The "USB" port is NOT a Universal Serial Bus. It is a SERIAL port using a USB connection!!!! What's worse is that Greddy is using some old or proprietary protocol in an attempt to control the market on laptop integration. Greddy will have you buy their "official" "Support Tool" which includes their "special" cable (see first pic of reply #445 above -- mine came with the cable missing). BUT, there are ways around this which I will share now.

For starters, you could just buy any ordinary serial cable, such as this $3 one on Amazon, cut one end off and soder on a USB male cable end from some old USB cable you have laying around......and then connect that to your 1990s laptop. But, at this point, I really hope you are not using a 1990s laptop or any other laptop that has a serial port! So unless you are reading this via your Windows 98 SE operating system, you could try making one yourself using a RS232 to TTL converter following the directions of this nice website. This is the cheapest (modern) option but I chose to get a premade USB to fake-USB cable from eBay, and this is what I did for $50: http://www.ebay.com/itm/291690440248 If for any reason you cannot find it on eBay or the link is dead, then here is the guy who makes them, http://www.ebay.com/usr/talon1luv, send him a message if you can't find it in his listings.



I highly recommend you get this cable right away because here is what happened to me: I was like 'No Big Deal' I'll just pick up a serial-to-USB conversion cable from Radio $hack (it was $39!!), installed the e-Manage, then realized there is some fancy protocol that prevents most all modern serial-to-USB cables from working, and returned the pile of crap cable. I then drove around for about two weeks with the e-Manage disconnected while researching what to do before I actually got a cable that worked!!

So I had the e-Manage installed yet I couldn't use it. Don't let this happen to you! Yes, there are some rotary dials on the front panel to alter AFM voltages at a few set RPM points, but....trust me, if you are not datalogging (much, much more on this later!) then I wouldn't even bother using an e-Manage. Seriously.

So without anymore sidetracking, let's get on with the install for the USDM (1988-1989 airflow meter and distributor 8.0:1 compression) 4A-GZE:

Installing:
Installing was pretty straight-forward. I have uploaded the Installation Manual to my server here:
http://bigmike.marlincrawler.com/files/1987_MR2/electrical/e-manage/e-manage-blue-installation-manual.pdf (PDF, 2.36MB)

Here we go! Let's do this in 3 Easy Steps

Step 1:

First open the PDF to pages 15 & 16. Unscrew the e-Manage and pull out the circuit board. Set the jumpers to the following:

JP1 1-2
JP2 1-2
JP3 1-2
JP4 empty
JP5 empty
JP6 empty
JP7 1-2



If you don't want to lose the jumpers at 4, 5, and 6 you can just hang them on one post off to the side so that they aren't touching any other post, like this:




Step 2:

Next rotate the board around to the end with the blue dials and flip to page 14. Configure the dials as follows (via info from page 27):

1: Position "2"
2: Position "4"
3: Position "A"
4: Not used, so point it straight up.
5: Not used, so point it straight up.



Then put the circuit board back inside the housing.


Step 3:

Next go to page 9. The top diagram is what our USDM 4A-GZE will use since we have a "flap type" air flow meter.



It is painfully easy. You only need to splice one wire, the AFM signal wire, and then connect power, ground, and RPM. The only thing to be careful with here is with the Airflow splice: The Green wire goes to the ECU, and the White wire goes to the Engine. Don't get that backwards!

Now, something VERY important here is that Greddy leftout the wiring for the Throttle! It is a Gray wire and will be needed if you want to base any adjustments by Throttle Percent, which does make sense as our positive-displacement boost is linear with throttle position.....but more on this later.

Flip to page 27 for our ECU pin layout, T-5, and you can see Th is listed for Throttle, which I'd recommend connecting. Colored for reference:



and here is a pin-out for reference just in case it's needed:



So that's it, 4 connections and 1 splice and you're up and running! Turn your key to the on position and you should get a blinking orange light at the e-Manage. At this point, as mentioned above, it would be great to connect the e-Manage to your computer before firing up your engine for the first time. So go ahead and plug your special designed-for-the-e-Manage-serial-to-USB cable to your computer now and launch the following software:

http://bigmike.marlincrawler.com/files/1987_MR2/electrical/e-manage/e-manage-blue-software.zip (5.53MB)

I've included the final update to the e-Manage Blue Software which will take the software from v1.40 up to v1.49, the final Greddy 2006 update which is required in order to run a MAP sensor without having to use some rainbow table to manually convert between AFM and MAP voltages (run "e-manage149 - update.exe" after installing the program).

If needed, here is the older PL2303 v3.3.2.105 Prolific cable driver that is old enough to work with the e-Manage Blue. This driver works with the cable via the eBay link above:

http://bigmike.marlincrawler.com/files/1987_MR2/electrical/e-manage/e-manage-usb-cable-prolific-PL2303-v3.3.2.105.zip (2.15 MB)

I've also included install instructions in the Prolific archive file (see step 1 below).

2. Get the software up and running

1. Get the Greddy Software installed and configured to use the same Com port as your cable, then close the program (see my install notes in the file '! Install - PL2303 v3.3.2.105 Old and compatible.txt').
2. Turn your ignition to the ON position to power up the e-Manage.
3. Plug the cable into your laptop, and finally
4. Launch the Greddy Software (again)

Okay now we'll move on to the actual software. Plenty more to come hopefully soon. I need to get out to my car to get various software screen shots to explain the next steps!

Regards,
BigMike

Greddy e-Manage Blue

Ok guys, let me tell you something, the e-Manage IS THE REAL DEAL.

With the USDM GZE, we can add fuel, add ignition timing, and remove ignition timing. We can modify the AFM voltage (however it's not recommended as this will also alter timing), and we can enter flow rates for oversized injectors and the e-Manage Blue (EMB) will automatically calculate the % difference for an adjusted AFM output signal (so the ECU sees the proper AFM signal as if we had stock injectors, yet we can add fuel on top since we've got larger injectors). This is everything needed to get the GZE running great on high boost and provides many tools for a great dyno tune.

A LOT has happened with my learning and progression of the EMB since September 7 so this is difficult to even start these next replies.

So I'm going to break this up into sections so I can organize all the progress with this major step in my car's development.

1. Configuring the e-Manage
2. Get the software up and running
3. Adding Fuel Injector control to the e-Manage
4. Adding Ignition Timing control to the e-Manage
5. Adding one accessory to the e-Manage
6. Datalogging from the e-Manage

and finally,
7. How I have been tuning my Supercharged MR2 with the e-Manage

I am going to find a way to jimmyrig my phone mount (to cut vibration) and film my times. I forgot to post it, but that same road up to heartland has a lower 16 -- 8.1 mile section that is great because there are not that many hairpins and is perfect for momentum cars - with the added bonus of just a few blind corners.

I posted this wrong the first time, below is an updated link - Start from the first dirt section to the right of the road where the double yellow lines end, and stop the clock as you pass the stop sign at the fork.
