I think I've decided to look for a new car. With all these issues and Nissan not helping, I'm giving up I think.

another mustang converter maybe?

Very likely. Can't beat it for the price!

Sorry to hear that... in fact, I was going to trade it in for an '04 NSX with about 30k miles. Price was under $50k, and I didn't mind ditching the forced induction idea to get the NSX and keep it N/A, but I was 2 days too late.

Anyhow, I've decided to continue the project in hopes that an ECU tweak for forced induction will alleviate this issue. It's definitely the only V6 I've ever owned that lacks low end punch that feels like it's computer limited (i.e., safety measures?)

Any new news on this? Getting more annoyed every day. 20k miles and the same problem. today was real bad. at least 60% of the time I went from a stop in 1st gear it gave me no power until 4k rpm. Usually it is more like 40% of the time. Seems that when this happens it is about 4k rpm that all of the sudden the power comes back.

So you can understand our pain it sounds like.
What years are they? Any mods? Also, what oil and filter do you and he use?

I am about to pick up M4s 370 today and I did notice the same thing a couple of times while driving on the test drives. As long as you roll into the throttle it doesnt do it but what i dont understand is why the engine revs so slow when using the gas pedal but if you let the syncro rev match do its thing the throttle response is instant. maybe there is something here so maybe its somewhere between the pedal and the ecu/throttle body

Just a thought
anyone agree??

I agree that if you roll into the throttle the car feels OK. You just have to train yourself to do that.

As far as the slow revving, I think it's just that electronic delay between your foot going down, progressively increasing the throttle, and the computer reading the potentiometer. With SRM, the computer just sends a command signal that basically says "5,000 rpm NOW!" and the engine reacts. With the throttle, the computer is reading progressive throttle input from 0% to whatever amount of throttle you give, so the engine isn't going to rev quite as quickly.

I actually disagree. I notice a delay with the SRM. What you may have to do is get to a cruising speed (I recommend ~50mph), put in neutral long enough for the SRM to "deactivate". Then put in 2nd. There is definitely a delay in it climbing up. I'm sure of it. It's just less perceptible since you aren't accelerating. It's only visual there.

The computer can get a reading from the gas pedal and respond in less than 1 microsecond. There shouldn't be a *perceptible* delay between reading the pedal and the car reacting.

Any more Group buy codes for this? Also will this work for the 2011 model? They say it's for the 2009-2010 but I assume it still should work.

Wrong thread?

thats probably why i never notice it either, i always roll on the gas, rarely ever just mash it.

haggomyeggo · 03-11-2011, 02:59 PM
