its been said 1000 times.. one more wont hurt.

ask your tuner. both will run the car just fine and do everything you could ever want, but if the guy tuning it doesnt know how to use it it's junk.

 

I also heard haltech as a PNP harness that will allow it to run in tandum with the factory ecu and retain your obdII port for emmission. I'm not sure if this is true or not. Can anyone confirm?

 

Not true; haltech is not making a harness. Some other companies are making them, though. They arent working perfectly yet.

 

My best suggestion to you is to ask your tuner. If you're going to compare features. I would recommend Haltech as it has a few more features than the AEM and is constantly being updated.

 

AEM Series2!!!!! We just had mine on the dyno with TONS of features hooked up and working flawlessly.

Just curious, what features does a Haltech have that the Series2 doesn't have?

 

Haltech isn't making the harnesses, FullBlown makes one that is OBD-II compliant. I used to have the Haltech PS500 with their harness. I did not get the emissions done while it was on so I can't say for sure if it did the job it was supposed to or not . Haltech just came out for 00-05 years on their Pro-Plug-In...

All in all, a majority of the tuners out there know AEM more than Haltech. At least in my area....

Like said, check with tuner. I vote AEM though.

Why not get the Kpro?

The Haltech PS500 has "most" of the capabilities as the v1 has; and the PS1000 has "most" of the capabilities as the v2 has. So I have been told...

 

I tune a lot of Series 2 cars. I like the Series 2. So this is an unbiased opinion.

Mainly engine protection features. Coolant temperature, oil pressure, coolant pressure, air temperature, exhaust gas temperature and the biggest one fuel pressure. You're able to do fuel enrichment, ignition retard, boost correction and/or a rev limiter based on all these with a definable minimum time. There are also features I as a tuner like that don't affect you.

 

SO as a tuner ud say the haltech is better?.....i spoke to my tuner on sunday he doesnt know much about the haltech but seems very interested in it.....i also know another tuner that has tuned on both aem and haltech and hes saying haltech is a better choice....just wanted to see what every1 else on here thought of the ecu

 

Either one is a good choice.
