i have a vafc2 with pnp harness for sale for 300 shipped of you need one =]

 

I still disagree. I think the AEM EMS would be a total waste UNLESS he already has several of the best bolt-ons. If he is nearly stock, then the benefits of the EMS over a VAFC will be too small to justify the price difference. Note that this is an AP1, which responds very well to the VAFC.

 

thdrew, I would really consider purchasing this used. If you decide to turn around, and sell it later, you could probably get the same amount for it again.

Your post doesn't seem to disagree with me really. I agree that a standalone will give great gains. However, I'm also saying that the AP1, which is tuned very differently than the AP2 from the factory, also gets very good gains from a VAFC. Sean Church was consistantly achieving 220's on his DynaPack by tuning AP1's with a VAFC, and my lightly modded AP1 put down as high as 214 on a DynoJet with a piggy back similar to a VAFC. Again, my point is that the EMS is 3 to 4 times the cost including tuning, but will only give a few more HP on a nearly stock AP1. I would not try to make the same argument if he had a good combination of I/H/TP/E, especially if it was an AP2.

 

Also, don't forget that the VAFC also doesn't cause the headaches that you have to go through for state inspection.

It would help to know what bold-ons thdrew has. Here is my dyno plot from before and after tuning with my custom piggy back that works similarly to a VAFC. Before and after were on the same dyno / same day. My bolt-ons consisted of an AEM V1 and a TP.

BTW, I consider swapping the ECU out once a year for inspection to be a headache. Of course, I'm not a small guy, so it was a significant PITA just for me to get the part number off my '08 ECU a couple months ago.

 

May I add AEM also give you other functionality such as launch control, custom dail back on rev limiter...

Some ppl just like to fiddle with parameters more than just a bolt on... It's not really like this will be his final mod...we all know once the mod bug is in, it quite hard to get it out.

 

Injector phasing? Is this advancing or retarding the injector pulse, like you would with ignition? I guess there is no way to do this with a FlashPro, is there?
