I am thinking of moving from the E6K to the E8 for various reasons. One being to use a new laptop (usb) and possible to introduce methanol/water injection.

-My question does anybody know how well the closed loop boost control works? I am using the apex avcr but thinking of selling it in favour of less clutter and better control.
-also does anybody know if you can use something like a scramble switch boost (ie press button and get another preset boost level like what is available with the avcr?) with the E8.
-also does anybody know how to set up the e8 as a fully mapable methanol injection?

Has anybody compared this E8 to other ems that are available?

Thanks
Ian

As far as a "scramble boost" you can get the trim **** and set the closed loop to what ever maximum boost you want and then turn down the trim **** to a lower boost setting. You could use the newer firm ware and enable the dual mapping and two completely different target boosts.

When you say fully mappable, do you mean as a multi parameter output of just a on/off system?? I am using the aux load switch to turn on my alcohol injection at 7lbs of boost, and then I have written the fuel map around the alcohol.

Here, have a read at this page, it indicates the total number of features found in the current haltech lineup, including the E8/E11. I would say it compares to a Motec M4, and with the new features found in the new software, you can greatly increase its versatility.

On, your boost question, the closed loop boost features is awsome on the E8/E11, and the boost control by gear i am told works great too.

It sure does and also being able to ramp the boost up by rpm helps a lot with traction!

I saw the trim function. Problem with that is you only have one trim available. IE I would like some sort of ignition trim. Maybe something like knock control of which it looks like the E8 has none. Nor the E11.

As for the AI. I mean fully adjustable such that its programable via load/rpm. Not just on or off at some set boost pressure. (Spray volume based on MAP PSI, TPS, RPM, and Fuel injector duty-cycle )


Look at FJO http://www.fjoracing.com/products/waterinjection
Now that is control Their EMS is also nice!

Thanks for your help.

Nice. Thanks for the response. Still trying to figure out if its worth moving from the E6K to the E8. Here is some questions I was going to ask. Some may have been answered already or seem pretty trival to ask. I think most of the difference is in what the software can do.

Questions
1: Software/firmware upgrades. Are they free for the life of the
product?

2: Boost control questions. Is it comparable to the Apex AVCR. The E6K
was not good at controlling boost. Is there a scramble boost function?
(IE switch to change boost map but not change the fuel! Like run 10psi
street press button and 15psi is set?)

3: Is there a section for automatic map selection. Say for fault
sensing (Lack of methanol in tank ) the map will change automatically
to a tuned pump gas map?

4: Can I have the ability for my car to run boost control, turbo timer,
A/C, Aux Injection (Methanol Injection) and ignition retard trim at the
same time. (Noticed the specs said not all things can be used at the same
time)

5: Is there a fully programmable water/methanol injection map available
that is tuned like a base map. (Do I have to purchase a separate driver
for this?)

6: Can I program a fault light to energize based on a warning criteria.
(High set points on coolant, boost, airtemp etc etc)
Or possible energize fault on boost/lean condition.

7: Why is there no knock control? IE sensing detonation retard timing.

8: Why is target fuel on a narrow band and not a wideband control? (Is
the option of autotune still available)

9: Can I use my innovative wideband controller (LC-1) with the haltech
E8. It looks the same as the available Haltech WB kit.

10. Is it compatible with the M&W or motronic CDI boxes?

wow. I guess not may people know the E8.

I've noticed the if you want trim control or map switching and wideband input you gonna have to pick only one. That sucks! Correct me if I am wrong. Also I cannot see any more then one aux in on the wiring schematic. Am I getting hit with the stupid stick?

Here are the answers from haltech!

To whom it may concern.

I have a few questions. Hopefully I can get them answered. Currently I
have the E6K running a 1988 Turbo Mazda RX7.

Questions
1: Software/firmware upgrades. Are they free for the life of the
product? Yes

2: Boost control questions. Is it comparable to the Apex AVCR. The E6K
was not good at controlling boost. Is there a scramble boost function?
(IE switch to change boost map but not change the fuel! Like run 10psi
street press button and 15psi is set?) Boost control on E8 can be setup to run in closed loop which is far superior to the E6K and easily comparable to the Apex unit. The E8 does have the ability to run a fully variable boost trim, so more like a **** that you turn down for less boost up for more. It is also capable of running multiple boost levels in different gears.

3: Is there a section for automatic map selection. Say for fault
sensing (Lack of methanol in tank ) the map will change automatically to
a tuned pump gas map? The E8 does have a dual mapping feature to allow for multiple fuels, this feature can be activated from a dash mounted switch.

4: Can I have the ability for my car to run boost control, turbo timer,
A/C, Aux Injection (Methanol Injection) and ignition retard trim at the
same time. (Noticed your Ad said not all things can be used at the same
time) Yes all these feature can be run at the same time. The E8 has the ability to run 4 dedicated outputs for this sort of a thing (called PWM outputs) there are 2 additional auxilary outputs that have higher current drivers on board that are also user definable giving you 6 fully definable outputs in total.

5: Is there a fully programmable water/methanol injection map available
that is tuned like a base map. (Do I have to purchase a separate driver
for this?

ANSWER: There is a map available for this in the standard features (located in the maps menu called the "generic load PWM output" this map will become available once one of the PWM or auxilary outputs is set to "generic load dc output"). No seperate driver is needed.

6: Can I program a fault light to energize based on a warning criteria.
(High set points on coolant, boost, airtemp etc etc)
Or possible energize fault on boost/lean condition.

ANSWER: Yes - Any of the options in the auxilary outputs menu can be connected to some sort of a warning light to alarm you to a particular condition. There is also a specific ECU diagnostic warning that is user definable that can alarm you of fault conditions on the air temperature, coolant temperature or manifold pressure.

7: Why is there no knock control? IE sensing detonation retard timing.

ANSWER: The reality is in a modified engine techniques for knock detection are not very reliable and rely on the engine to detonate before the sensor registers for the ECU to start retarding the timing. A better solution is to tune the engine correctly to the point of minimum best timing (MBT) to gain maximum power output yet avoid detonation all together.

8: Why is target fuel on a narrow band and not a wideband control? (Is
the option of autotune still available)

ANSWER: Narrowband lambda is used by all OEM manufacturers for idle and light load conditions to allow for correct catalitic converter operation and fuel economy. Wideband O2 control is also available on the E8.

9: Can I use my innovative wideband controller (LC-1) with the haltech
E8. It looks the same as the available Haltech WB kit.

ANSWER: Yes

10. Is it compatible with the M&W or motronic CDI boxes?

ANSWER: M&W Yes - Motronic i have never heard of, perhaps your talking about motec??? if so then the answer there is yes (the motec box is actually just a rebagged M&W box).

wrong, an e8 has 3 A/D inputs, they could be used from any combo of trim controll or wideband, or other things.

There is also an aux input which could be used for map selection AC request and other on OFF (think digital) type things.

I think you can even free up an additional input by connecting your wideband to the o2 sensor input instead of a digital ad, at least with halwin 1.71 (don't know if this would allow you to datalog LAMBDA, may have to datalog voltages), there is also a timed digital input normally used for something like road speed, which can also be used for anything the AUX in can be used for.

I have an unproven but working theary after seeing 2 disasembled ecu's an e8 and an e11 side by side, that you could probably have all of the inputs an e11 has by just changing to an e11 wiring harness and running e11 firmware.

There's always Excel to view your datalogs in AFR, converting them from voltage with the help of the formula that manufacturers include in the literature for the brand you have.

Gear based boost control you need the timed digital input. Down to two. Then A/C needs one. Down to one. Before you know it you don't have any more. LOL

slo

iTrader: (1)

If you use gear based boost control, and AC request (you really don't need to have the AC request go through the haltech), then you still have the 3 A/D inputs. Use the 02 sensors input for the wideband, still have 3 ad's that could be one for Boost control, and one for Timing trim, which could also be used as a knock detection timing retard (very easy to hook up using most knock detection systems), that still leaves one for switching maps or whatever else you want.

If you want 8 inputs each for A/D and Aux, then get an E11.

crispeed

That's exactly why the E-11 exist.

ikari899

with the new firmware you can only view and data log lambda.

Any suggestions? (See picture)

I don't think you have another option other then using the trim input A/D #2 if you want to display A/F ratio's and datalog.


I realize the E11 has more I/P and outputs but had various people say that the E8 will do more then you need for a rotary.

I think the idea is that not many people run A/C which uses up the AUX in and AUX out removing the ability to run antilag/turbo timer option and maybe something else.

I asked haltech if I can run a warning system IE if I hit a set amout of parameters if it would turn on a light. Their answer was yes. It's sort of useless since its only function is a PWM out, on only one parameter at a time like say a high coolant temp. I don't think its logical to only have one selection per PWM out. It would be nice to be able set up say turn on a light if I hit a setpoint of either one of the following: high coolant, high air temp, high boost, lean condition on full throttle run, lose of water in AI etc. This way you are aware of an issue without have to constantly scan a billion gauges or such. (Or am I just asking to much?)
