Ecutek tune concern

littlejuanito

I got my car ecutek tuned recently and although the car felt perky and fast initially, now I few hundred miles in, the car's power feels somewhat the same as before the tune and not as snappy and powerful..

What could this be... Placebo effect originally? Maybe I got used it? Car pulling timing, if so. Why?

For reference, the issue is the same whether in cold or hot weather, traffic or high speed and I've used the same gas, Shell 91 octane.

Anyone experience this?

I'd talk to Seb about it. I'm on ecutek by him and haven't had this sort of issue. Please keep this thread updated though

Well, I definetively knew something was wrong as I just got an SES light and the car feels stock now. Will resetting ECU help?

littlejuanito

Code scanners can be had for cheap ($20-50). If you are going to be doing any trouble-shooting, a scanner (or more sophisticated logger) and the FSM (it's free) are must-haves.

Yeah I sent him an email. Hopefully there's something he can do remotely. The car now feels like crap and doesn't sound right

In the meantime, you can also have the code read for free from most local auto parts stores (Autozone, CarQuest, O'Reilly's, etc.).

Thanks swisscheese. I'm going to Specialty Z tomorrow. I spoke to Seb via email and he said it may be a leak somewhere and the O2 sensors picked up in it.

I'll update once I'm sure what it is

Yea you can't really blame a tune for a poor install or parts failure causing a running concern. Fix the issue not the tune.

littlejuanito

Update: I took the car to Specialty Z and everything was fine in regards to the HFC installation and there were no exhaust leaks either. Turns out it was a combination of a few things that made me throw a code. Let me explain, right when when this happened, I was running on MAP 2 (aggressive mode) when I decided to pump Costco gasoline, which I was told I shouldn't have used. This, combined with the fact that it was literally 112 degrees in Cali, was the perfect combination to make the car run like crap and flash a SEL.

I was recommended to use better gas such as Shell or Chevron and to always run the "Hot weather map" when above 95+ degrees outside.

I did as told and once I finished the Costco gasoline and the weather got cooler, I pumped some Chevron fuel, switched to "Aggresive mode" and now everything is back to normal again.
