I need to know if the SRT piggyback ecu just remaps the
air flow sensor or if it also leans out the fuel. I am considering
adding a 50 shot of NOS and want to make sure that the
piggyback isn't going to make the fuel mixture to lean.
Any help would be greatly appreciated.

 

yeah..u need to use a wet kit...

Thanks for your reply, It is going to be a wet kit but I want to
make sure that the piggyback ecu does not lean out the fuel mixture and make my car run to lean to add the nos.

 

I don't work for a51 nor srt so I cannot say for a fact, but I'm fairly certain both intake/ecu's lean the fuel a bit.

 

Thanks for your help. I am going to call SRT and see how much and if it will cause problems with the NOS.

 

Tampa, you shouldn't have any problems, I have an Apex SAFC/W an Injen intake and it defenitely leans the fuel. I don't have any problems. I made sure of this on the dyno using the rich/lean indicator. This tool helps you monitor in real time your a/f ratio at any gear, and any given rpm point. In fact my car's first run was lean, then I changed the jetting around. The NOS fuel solenoid is going to be the one your going to play with the most. Now it's running a litlle on the rich side. Which is safe.

My best advice to you, go to a dyno which has the a/f ratio sensor. And make sure you'll be running good, but safe.

GOOD LUCK

 

Thanks for the info H/B.

I cant find anyone, I will be visiting your friend at toyomoto.
