How often do you have to Premix?

Someone also mentioned about www.k2rd.com plug and play harness for the FD. Is it better to get this setup?

Also, how much does it cost to install the Haltech? For example, my engine is out of the car, so I'm assuming it would be slightly cheaper right?

 

What about the issues w/ the Haltech and ignition timing. There has been much said about the PFC being much more accurate w/ ignition timing than the Haltech. Might the Haltech be a potential problem when running tight or zero split timing?

 

Actually thats the exact opposite. Dave at KDR blew two of my motors due to faulty timing issue's with the Power FC. He then suggested I sell the Power Fc and get the Haltech which I did and I havn't had a problem since.

 

Rice Racing on this forum says the opposite. He dials in Haltecs with more split than PFCs because of their inaccuracy. Also there have been numerous threads as to Haltec's inaccurate timing such as this:

I'd like to get to the bottom of this

 

We need some of the big tuners to tell us what they really prefer. Also, to give us the pros and cons with these units. Dave told me that I will be fine with my setup using my Power FC, I guess I just have to wait and see what happens.

nobody answered my questions. There pretty easy questions for you guys.

 

Jay,
I buy the Protec R from Pettit cause its easy and already in 4oz bottles for you. One bottle per fill up. Costs about $20 for a case of the stuff.
As for the plug and play harness. You would loose some of the sensors the Haltech has over the stock harness, not to mention how much cleaner your engine bay will look, but it comes down to what you want. Dave charged me $800 for the install with my motor already out, so figure about that much for the full install. Only thing Dave did that I didn't like is he re-used the mazda sensors which are very expesive if they go up as opposed to the GM sensors that come with the Haltech and cost about $4.00 a piece.

 

What if you are trying to stay emissions legal? Then the haltech is out of the question, unless you use it as a piggy back on the stock ecu.
The PFC allows you to stay emissions legal.

That is a big factor to me, although i still haven't decided on an engine management system.

 

well exactly how *innaccurate* coule either one be? The power FC plugs in using the Mazda CAS, not sure about the Haltech but am sure its the same. At the minimum they both are as accurate as the stock ECU which will run timing very accuratley.

 

Actually, I doubt the problem with timing was from the PFC not being able to control it. The problem was probably in the harness and was fixed when you replaced it.

No, your wrong. There were no problems with the harness. Dave showed me how he bumped the timing on the power fc, but the original timing on the Power FC was an estimate and not actual (his words). And therefore when he advanced the timing while tuning, it was advanced way too far.

 

So whos the online retailer for Motec. Seems like the only things bad people have to say about them are they are expensive.

 

Ive heard this to be untrue, which is the reason im still getting one. If I wasnt sure I could pass emissions, I wouldnt order it tommorow. And you can bet your sweet *** im ordering it. Ive been convinced by ReTed its possible using an airpump hooked up to the cat. Where do you live that you cant shove a few bucks in someones pocket anyway?


I hope youre ready to sell a ********.

 

I heard to stay away from the Haltech. A guy who does rotaries for a living (Stan at SDJ Motorsports) said he had HUGE issues with getting the Haltech to work correctly and he really wouldn't suggest it. He said go with the HKS.

 

Go with the HKS what? HKS makes good stuff but that is because most of it is manufactured by someonelse, usually a foriegn company in the US or something.

Why pay HKS for a Garret turbine when you can get it cheaper from Garret. IN my opinion the Haltech or Power FC blows (im assuming) the Fcon V out of the water.

Anyway I would like to hear more about the timing resolution on both of these units.

 

i've got a pfc and single T04s. I'm gettin 365 rwhp with a street ported motor at 15 psi. I got the maps from XS and the car runs really smooth. Dave at KD said the maps produced a perfect AF ratio. I do think however i could get a few more hp out of it. I read there's a guy using a pfc/to4s with 419 rwhp at 17 psi in ohio somewhere. He actually got it up to 460 rwhp but running way too lean and unreliable. I'm happy with it but just for curiosity sake, i'd like to try the haltech one day. Do you think it would get me more hp?

KNOCK KNOCK, look at the MASSES of people who run Haltech E6K's on this forum alone, Look at how many people world wide are running E6K's and making 400+ HP, Now how many people can you say are runing HKS engine managamenet systems? I cant name a SINGLE person.

Unless you spend the $$$ and buy either an Autronic or a MoTeC, you cannot get better results than an E6K will provide, PROVIDED it is tuned by a competent tuner
