a week old log of 27psi peak boost showing what *typical* idc should look like towards the higher rpm range. Keep in mind this is with low peak timing and a 625 nozzle of meth running straight 100%meth @ 12.5 (a/f +/- 2)

If you're saying your at 20%idc at anything above 4000rpm then you're probably not calculating properly.

 

This is with stock injectors or?

 

Stock injector.

 

Jeff, I run a 325 nozzle and I have to pull fuel to about 12 (AFRMAP) on the map to get me between 12 - 13 on the WB. If your pumping that much fuel and air then I'm putting the stock cams back in.

 

Load up your pump tune and log it with the kit off... Then log it with the kit on... with the m8 nozzle it should be around a point richer. If its not then something is off...

Cheers!

 

Not sure what your meaning.

It appears your looking at map numbers. I thought the numbers on afr map in ecuflash were only relative to the car and its actually afr. Basically some ones 12 could be someone elses 11 ='ing a 12:1 AFR.

 

That is true, but if you are on stock injectors & stock turbo, then your fuel map should not be drastically different than someone else with meth also on stock injectors & stock turbo.

Usually, a stock injector fuel map on a stock turbo will have values in the 10's in the fuel map. Add meth injection and this will have to be leaned out to 11+.

Take 4WS's advise and log a pull with meth turned on, and without. If your AFR's are not richer with the meth turned on, then something is wrong with your injection.

 

I got logs from the pump gas tune, and when I logged my meth runs after install there was a def fatness in it. I can look and see. No doubts the alky is working.

 

I posted two logs of the AFR one with meth and boost turned up, which obviously leaned it up some, then adjusted the afr leaner and logged it. Both on the bottom of page 1.

 

On your injection pump, where is the set screw set to?

 

have you done the log meth on log meth off log?

 

Sorry guys been sick all week.........feeling better today. I plan to check the pump pressure setting.

I know it is using the meth, I have a pretty decent sized tank almost two gallons. I have used almost one gallon so far.

C6C6CH3vo, you got PM.
