Reason I post it here is because most people running a haltech e8 are most likely going to be running a single turbo. Rather than posting in the haltech forum where it is more than likely biased, I thought I'd post here to get some personal experience from people running singles and have a tuned ecu.

Currently on the PFC tuned by Kan. I am happy with Kan's super rich tune.. lol, the car has great power.. but I am debating on keeping my current setup or switching to the haltech for several reasons.

I would like to know the opinions of people who have used a PFC and switched to haltech. Or had experience with both EMS and can give me their personal opinion.

ALso, what does the haltech require when doing the swap.

So far this is what I hear i need:

Haltech E8 ECU
Flying LEad Harness
Bosch LS1 Coils (have these)
2 Ignitors
TPS Sensor
Air Temp Sensor
Water Temp Sensor

Also, how easy is the halwin software? I'm pretty familiar with the datalogit FC Edit software though.

Would it be worth doing the swap from PFC to Haltec?

I hear the haltec has built in 2-step, and a wider area for tuning.. (32x32 rather than pfc's 20x20) - I've also heard it has questionable timing accuracy. But I have yet to hear any first hand experience.

Thanks,

The Haltech E8 is a great choice.
First, you will get rid of the messy OEM ecu harness.
Also, no need for ignitors when running the LS1 coils. Just wir ethem directly. No need for a TPS sensor, you can use the fatory FD TPS sensor. No need for coolant temp and airtemp either, you can calibrate the factory ones to work. But I put new ones Haltech units) just to make sure they are accurate.

The Halwin E8/11 software is really easy. The timing accuracy issue was adddressed back when the initial E11 was released and now all boxes are great.

The Haltech software has bigger maps, better split map, it has 2 step, antilag, fan control, etc etc. It is better overall, especially for your setup with the HKS T51R KAI. You can run dirrerent coils, ignition boxes, big primary injectors, etc etc.
The PFC is a GREAT computer for a daily driven 400-500whp rx7. Above that level, it is a better idea to move to a Haltech, Microtech, Wolf3D, AEM, Autronic, or Motec.

I have tuned many PFCs with the FC Pro Apexi original software, and now I have an E11V2 for my GT42R 13B.

 

if you're referring to the bosch coils in the pic you sent me, you'll need an ignitor. those are the ones microtech sells and they need an external ignitor.

 

Haltech air/coolant sensors are more accurate than mazda's and no need calibration

There is the info page for the E8. It will answer your questions about all the available features like the 2-step, anti-lag, etc. One of the most exciting things about the E8 for me is the ability to do closed loop boost control and now intergrated wideband contol. In short it's a much more full featured unit than the PFC.

I would recommend installing the Haltech coolant and air temp sensors but using your stock FD TPS. It's a capable unit and it's already mounted relieving yourself of that chore. Calibration of the TPS is very simple.

As has been mentioned the LS1 coils are the easiest to use and are quite capable. The 2nd gen coils can be used and can usually be had inexpensively but are quite bulk to mount.

You have a PM as well.

 

Those are the coils, I might have to get an igniter or find a set of LS1 coils.

 

just get an ignitor. we already talked about the ls1 coils.

funklove-- i use the air temp, but i usually use the stock mazda ect. no drilling, no tapping, and how often have you ever seen one fail? and even if it ever did fail, it's $20. all i had to do was set the calibration once and it's good to go.

 

What is one typically looking at cost wise for a complete E8 setup? Computer, complete ready to go wiring harness (if anyone sells them that way), LS1 coils, and sensors? Does any wideband work with the Haltech?

 

I'm running a haltech E8 with my single conversion. it's a great setup. I used stock tps, and coolent sensor. No prob! But using the haltech Air temp sensor.

This install is great and i'm soo happy i went this route cuz when i took out my stock harness and seen the condition i was amazed how shiity it was!

also using stock coils with hks amp.

The e8 has soo many more options and is much better when fully tuned compaired to the PFC. Has many nice featueres like anti-lag, launch control..etc

 

~1600 or so, with the haltech wideband.

 

What about OMP and a/c control? Do any of the vendors make a ready to go harness for the FD?

 

Haltech does not make a ready to go harness for the FD, they do for the FC though (at least according to their webpage) - most installs cost $1000.

 

i know, you can give me the haltech, i'll slap an fc front cover on that renny engine and do an fc project, then i'll make a darren sticker and tell everyone you sponsored me

 

A Darren sticker? What's that going to look like (i know I'm asking for it)

 

you'll see

 

Can you talk more about the fix with timing inaccuracy? I have an E8, is running zero split safe on an E8 now?

 

Do you know this thread is 14 years old?
