Now, I have my 3rotor racecar running a Haltech E11v2 and don't have any of the problems described above. Can any of what he's saying actually be verified/proved or is it just nonsense regurgitated from the mouth of a Motec dealer? I'm going to leave him anonymous for the time being, but he was previously running a Microtech (not sure which one).

 

"We tuned every 250 RPM from idle to 8500 rpm"

You can do this with an E11/E8...

 

He probably never worked with an E11v2 or even an E8 before and is going by old E6K standards, which were good for its day but nothing compared to the resolution of the E8/E11v2.

I have talked to people who have gone from a 689hp 3 rotor with Microtech and have told me that the difference is night and day making the same power (perhaps more). The simple fact is that a microtech is a very simple system, its got far less resolution than even an old E6K/S and thats why that difference is felt when upgraded to what ever system with more resolution.

The fact is that a Haltech E8/E11 can do just about everything the Motec M400 and M600 can and just so happen to cost half as much.

I can guarantee you that guy has not taken the time to sit down and do the same thing he has done on his 3 rotor with an E11v2 so he can see the difference (or capabilities).

With a Haltech you can properly control your idle, midrange, high end, split, corrections, have auxiliary accessories, etc. etc. etc., and it will do it all very very well.

You said so yourself, you are not suffering from any of the so called "problems" he talks about, and i am willing to bet that your car can be tuned to what ever potential he can think of that is within tolerances of your motor. He's probably very passionate about Motecs, i know they are a great system and they do the job well, but Haltech is also a great system and the E8/E11, and now the Platinum, are top notch.

 

I don't see how one EMS can dramatically increase peak HP over another. Driveability, sure, I can see that, especially if one EMS has better resolution than the other.

Also, his is not a fair comparison. He's already introduced other variables than just the EMS into the equation. He's changed coils and TPS, so both power and driveability could increase from just that alone. We haven't even considered environmental factors, such as ambient temperature and humidity, between the dyno runs with the different EMS.

 

Yes, this sort of discussion is like a "chicken and the egg" thing.

Its all very very relative, too many things come into play.

But, the important thing is that for example, an EMS with 16x16 resulution and a 16bit processor will not give the same results as an EMS with 32x32 resolution with a 32bit processor.

And finally the MOST important factor of all, the guy behind the keyboard, its very likely that if the person behind the laptop knows the EMS back to front, upside down and backwards, he will be able to do a good job on the tuning, regardless of the system, but a better system will give better results.
