Im not to up on ECU and chips. I was wondering what I have to look for when getting one?

 

I have forged internals, 740cc injectors, GT28R tubs.

 

The reason I ask is BAZZ has a Socketed ECU and 740cc chip for sale and was wondering if this would be ok? Does the type of chip matter if running a AFC and dual intake with a dummy MAF?

 

Thanks,

The voltage only maxes out as the element is reading its max flow for a given pipe diameter:

Range of voltage is 0.4-5.12v from the maf.

Put the maf in a bigger pipe of diameter y instead of original x then the max airflow read at 5.12v is increased by the ratio of the areas so (x/y)^2

 

Ah - ok. Makes sense now. So you just need to remap to the increased diameter of the MAF housing?

Just as an FYI, I used to run the JWT twin pop setup with dual AFM's and used the AFC to 'add' the airflow. Worked immediately without changing ECU and no running problems.

 

Will caveat that this setup was only used up to around 400bhp, am now running a MAP sensor instead on the AEM.

Jimmy, chip should be done tomorrow, not sure when you'll get it with the Xmas break etc.

 

Looked into the Lightening MAF and it should be good for about 700bhp and should fit quite nicely. Will see if I can get a price on it for a non-exchange part. Should be cheaper and more available than the Q45 one too.

 

is this the maf your talking about john?

i would still need a reducer and 80mm pipe... same with the q45 maf, the q45 maf is available for about £80 and i think the air filter im using now can still be fitted to it with out the need for an adapter... What you think John?

 

One thing im worried about is the filter sticking to far down sucking in water not to mention the turbulence it will produce. any thoughts on this John?
