Hey guys, i ran into these issues today while installing an E6X on a client's FC. I connected all the sensors and wired up the CAS, but when i was attempting to calibrate the throttle it it would read properly using the factory S5 TPS (the full range one) but after finishing the calibration process the software indicated that the range of the TPS went from 6% to 84%. I tried calibrating it several times with the same results all the time, i tried plaing with the adjustment screws on the throttle body with no luck.

The other issue was that when i was setting up the ignition and trigger settings it didnt allow me to set the "ignition toggle ON" check box, it kept giving me an "invalid operation check other settings" messages, i went over all the settings in all the setup window, setting the correct ignition type, etc, with the same error message all the time. And yes, i did set the aux out to "Ign. Toggle".

Any ideas? Ah! and finally, are there any Firmware updates for the E6X that i should be aware about?

as for the callibration that is pretty much normal... as long as you callibrate it properly the haltech will automatically condence the range so that 6% is changed to 0% and 84% as 100%. so that is no big deal.
what version of the software are you using?

I know that, i tried to calibrate it a few times, it always showed the 6-84%, it didnt reset to 0-100. That is the weird part.

Im using Halwin1.2.

The HITman has a firmware updaterd utility and latest firmware revision for the X and E11, i was wondering if i should applythis. Guess i should just write haltech and find out.

A-HA!! Eureka! ive found it! apparently when setting up a rotary withe the toggle feature, you need to set the fuel mode to "Sequential" of all things!!? I didnt know that! Duh!

Well, resolved that one, but i still have the TPS calibration hickup to worry about.

Ok, i emailed haltech about the bugs, they indicated a few tips to tryout, also the TPS deal apparently has something to do with having the engine data text page window opened so it has to be closed for te value to reset.

Will try all this out in a few minutes and will post all the end results here.

Well, the car starts. All the bugs have been covered and the car is purring nicely. All i need to do is tune it with the wideband, that will follow tomorrow, when i do i will post the driving experience. Here is a recap of what i went through.

INSTALLATION:
1. Installed the unit.
2. Wired up all the sensors.
3. For practical reasons, used the factory water temp sensor, later it will be tapped and the haltech sensor will be used.
4. Wired up the CAS using the Haltech's own trigger/shielded wires, not the original harness wires.
5. Wired up the coils using the factory wires for ease of installation. Wired them according to the "toggle" option advised by Haltech.

CONFIGURATION:
Settings for this application are as follows:
MAIN:
# of Cyl.: 4
Load sensing and type: 3 bar map sensor
RPM Limit: 8000
Cylinder Mode: Rotary
RPM Limit type: Ignition
ECU Mode: Advanced
RPM Mode: 10500

FUEL:
Decel Fuel Cut: Disable
Injection mode: Stagging
Ig/By: 2
Stagging bar: 12
Zero throttle maps: Disabled
Baro. lock: enabled @ 1013mbars

IGNITION (this setup is specific for factory CAS/Coils/Ignition Modules):
Triggerangle: 65 (may vary with your app.)
Tooth Offset: 3 (may vary with your app.)
Ignition Spark Mode: Distributor
Spark Output: Constant Charge
Spark edge: Falling
Dwell: 3.1ms
Internal toggle and coils on 4 cyl. motor checkboxes unchecked

INPUT/OUTPUT:
Trigger angle: 65
Trigger type: Multitooth
Trigger imput: Internal Rel.
Trigger Edge: Falling
Trigger Gain: 1-3
Home input: int. rel.
Home edge: falling

WIRING:
The CAS is wired as per instructions (wire colors are inside CAS):
CAS -- Haltech -- Function
Red -- Yellow -- Main Trigger +ve
Green -- Green -- Home Trigger +ve
White -- Red -- Main Trigger -ve
White/Black -- Blue -- Home Trigger -ve

The Coils are wired as per "toggle feature" (using the car's own harness to the coils, colors are from the 86-88 harness):
Coil Wires -- Haltech Wires -- Function
Green/Yellow -- Light Green -- Leading Coil
Blue/Yellow -- White/Black -- Trailing Coil
Brown/Yellow -- Green/Black -- Toggle select

With all this proerly wired up and configured, and a proper fuel and ignition map loaded, and provided you zero in the timing right, the car should now start and run right with very little effort.

After all is said and done i got the car started today, and idling fine, tomorrow i will double check the timing and tune the car for street duty, pump gas and around 10psi of boost.

The car is an 87 FC3S with a 91 turbo engine, completely stock, later on the owner will upgrade injectors, turbo, intercooler, etc.

The final conclusion is pretty clear i guess, its all in the installation. What i hope to prove here is that the E6X can be properly installed and tuned on our old cars with the proper proceedures, wiring and setups.

I'll follow up on the progress on this car so you know where all this ends up. If you have any questions please feel free to post or contact me.

I don't think one case makes it pretty clear. I did mine install nearly identical with the same settings.....

these where my settings (with the corrections implemented)
https://www.rx7club.com/haltech-forum-62/install-settings-e6x-387833/

It was wired up correctly too as it was running once cas signal randomly decided to pick up.

I will admit that the trigger circutry found in the X does have a tendency to pickup more noise than the E6K, i only hope that Haltech revises the design soon. But what i want to addess are these reliability issues i keep reading about. That's what im hopping to learn from this install, hopefully it will work well in this car and i can sell more of them.

Sesshoumaru

iTrader: (1)

The noise issue doesn't bother me as that is something I can have a impact on.

What gets me is not picking up any signal for 20 tries. Then works flawlessly the next 6 tries. Then not work the next 10 tries with changing nothing except shutting down halwin in windows.

Claudio RX-7

iTrader: (1)

You mean trying to start the car will start fine sometimes and then not start other times, then start again later?

Does this happen with the Laptop hooked up to the ECU or all the time?

Or are you talking about communication between the laptop and the ECU?

Sorry to ask, i know you have another post around here about that, i just havent read it. :$

Sesshoumaru

iTrader: (1)

where the dice rolls and the wind blows.....

I couldnt' tell why some times it did and other times it wouldn't pick up.

Communication between the pc and ecu was fine. The last thing I can check to see if the harness was missed pinned. I have plenty of time to do that while the ecu is getting shipped back.

Don't get me wrong... I like the e6x and will run one in my FD but I think they should have taken a bit more care and spent a bit more money on certain things where they skimped.

Claudio RX-7

iTrader: (1)

Well yes, i have to agree, and since ive been told the E6X is basically the same as a K but with different hardware and firmware, and knowing how the E6K is a tried and true workhorse my guess is that they should've just kept it as is.

I cant wait to see the new E8.

Sesshoumaru

iTrader: (1)

I have not heard of the E8 yet.

I'll have to browse their site while i'm at work

Claudio RX-7

iTrader: (1)

Here is what i've been informed officially about the E8 and some new up and coming items from Haltech. Also the Spec Sheet is on the Haltech Download section.

Here are a few details on E8 and upcoming products.

NEW E8 - The all new performance ECU.-

The E8 is packed with more features than any ECU in its class by more than just a quarter mile!

The all new E8 performance ECU is for those who are on a budget and need full sequential control for their engine.

New Features include:
- Soft cut rev limiter
- Closed loop boost control
- Tuning via TPS with Manifold pressure correction - Ideal for those multithrottle body turbo cars such as, GTiR pulsars and GTR skylines.
- 32x32 mapping structure
- User definable mapping points
- The ability to calibrate just about any sensor for OEM applications and of course all the usual outputs you would expect to find in a Haltech engine management system.

With 4 dedicated fuel channels (each capable of running 2 low impedance injectors or 4 high impedence) and 4 dedicated ignition outputs the E8 will be most feature packed ECU in its class and is set to be the best value performance ECU on the market.

Haltech Plug-in looms are just around the corner.-

A whole new range of plug-in ECUs will turn the engine management world upside down. Never has such performance and ease of use come together in this way. With many popular models currently in testing this is finally the product that we have all been waiting a long time for.

In time, all the common vehicles will be covered. The first wave of plug in adaptors will include solutions for:
- Nissan Skyline, 200SX & 180SX.
- Mazda RX7
- Mitsubishi Lancers
- Subaru WRX
Just to name a few!!!

Not only will installation be simple, base maps will also be provided for turn key installs on most vehicles in a matter of minutes.

The great advantage for you and your customers with the plug in adaptor loom, is the ability to go back to factory settings in a matter of minutes if the need arises. Also, if your customer sells their car but wants to keep the ECU - that's fine. Just ring and order another adaptor loom and bring the ECU they already own in to plug in and start tuning.

What do I do with the GOUND and other leads marked IGN OUT...Just dont use them?

eViLRotor

iTrader: (2)

Yep.
The Ground goes unused. You can just cut it, or tie it off.
The other ignition wires are unused as well, except IGN3 which can be used as a DIGITAL OUT for you efan or whatever.

I think i posted in on another post somewhere, or on the Haltech Board, but i have noticed a HUGE difference in trigger noise reduction/RPM spikes elimitated/engine running smoothly when i use the lowest possible gain settings that would allow the Haltech to read from the CAS. I was using 2, 3, etc, and the dam thing sounded off, it reved, but had some oscillation, when i lowered the gain to 1 and reset the ECU (turn ignition switch off) the difference where night and day, perfect running engine, smooth ilde and reved beautifly.

I might advise ALL E6X users to try that and see what happens.

I have been running a gain of '1' since almost the beginning, and it was running perfect. But the last few days, I was getting some weird trigger errors on my 6X. At about 4k rpm it would start to jump like crazy(and the car would backfire).

It has been really hot out, and magnets tend to get weaker with heat, so my friend and I decided to move my CAS magnets closer to the teeth.

This, combined with a gain of '0' seems to have fixed the problem.

His 6X car also runs best with the gain set to '0'.

He is going to work on modifying the stock CAS to work as an optical trigger next, maybe solve these problems once and for all.

Claudio RX-7

iTrader: (1)

Interesting work, thanks for the feedback!

Sesshoumaru

iTrader: (1)

That's exactly what I did (move magnets) but still run a gain of 1.

Car runs great now.

BASTARD

iTrader: (4)

what about wiring up the idle control solnoid

Sesshoumaru

iTrader: (1)

I never did.

Idles great after setting throttle stop and fuel.

i didnt know you could use the stock s5 TPS....
would you tell me how to wire it up??

I havent looked at it yet so this may be a pointless question.
sorry if it is.




e6x install underway on an s5 motor in a first gen rx7....

Claudio RX-7

iTrader: (1)

Simple, just take the 3 wires from the full range tps on the S5 throttle, i forget the colors, and splice them to the haltech tps wires, orange for 5v, black for gnd and white for signal.

I think the colors on the S5 TPS are blue yellow and pink.

G_RIDE

that would be wired as the positive trigger for the relay correct?
