Mia....does the re-flash clamp the voltage seen from the MAF by the ecu?? If so, what do they clamp it at?? Higher than 4.7 volts on the UTEC??

 

No the reflash does not clamp the voltage at all. Are you sure the voltage clamp is not adjustable on the UTEC? It is on the Emanage and other tuning

 

Nope....checked with Sharif and he confirmed it is non-adjustable on the UTEC.

How is it then that the car does not go into limp mode with the T-netics kit without a voltage clamp??? The airflow of a boosted car should max out the N/A MAF at only a few PSI.

 

it doesn't until 6-7psi.

 

mine doesnt max out the maf until right over 10 psi. plus mike, even though it "says" that if you put the utec on map 0 it is running stock, well it isnt, the utec still does some weird stuff.


it made my NA car run like crap on 0.

is the parameters on the utec set to take over at 20-25 percent throttle??


if so the maf has nothing to do with the injector pulse widths any longer

 

If this is the case then why do the UTEC and the Greddy E-manage clamp the MAF voltage under 5.0 volts??

 

Mine did the same thing but in the rain. It did happen the next day when the day was nice. The AEM filter that came with the kit is not oil based and after opening up the pipe for the MAF, I saw water spots all over it. I didn't drive through any ditches of water, just hard rain. I actually switched out the filter to a K&N one since it is a oil based filter. Anyhow, could have that caused damage to the MAF??

 

yeah, i am going by dataloggin using 1 on the utec and following the psi verses maf voltage, it will max out at 5.0 on mine but it does it right over 10 psi. thats why i think its crazy when people are saying they are close to maxing out the maf NA..... right...

 

Mine maxes out at 5.0V as early as 3800-4000 rpm with 6-7psi of boost.

unfortunately, boost isn't a very good reference to look at....as boost is not related to airflow. It is only a measurement of pressure in the intake mainfold.

A very basic ananolgy would be this: it will take twice as much airflow to make 10 psi of boost at 6000 rpm as compared to 3000 rpm.

whatever your case may be, you will definately max out the stock MAF meter with only a mild amount of boost at mid range rpms.

 

On the dyno in Cali Turbonetics ran my car up to 12 PSI before the MAF maxxed out.

 

I am going off of my UTEC datalogs.
