I got a few questions ..

OK.. I got a lovely 76mm MAF tonight. The sample tube in it is designed for 24lb injectors (I am still running 19lb). I wasnt sure if it would run right, but low and behold - the thing actually works.

The shocking bit - is it actually runs better!!.. The car still has a few issues starting, but doesnt stall at every traffic light.

OK.. I am going to get the 70mm TB soon (when funds permit), but I am curious about the injectors now.

Should I put on a adjastable fuel regulator? (19lb injectors can be pushed out to run 22lb).. or should the unichip be able to be reprogrammed to compensate?

I know at the moment my car will be running lean.. so I am taking it relatively easy (no drags for me for a while).

Nice pickup there Kelli.

I say just get the proper sample tube soon as possible and maybe get it retuned by the unichip people to smooth out any load problems. Adjustable regulator isn't worth the money but you should certainly look at upgrading the injectors when you get that intake changed.

How was Sam's car running with the stock MAF? I'm guessing it would have been pig rich with the stock ECU and those 24lb injectors, haha.

Way to go!! Early Birthday Pressie????? :-)

It will run lean but it will try and compensate a little for it. I was running a 70mm on mine for while and air/fuel was around 12.3 at the bottom end and 13 at the top end. They should be able to smooth most of it out with your unichip.

Running the bigger injectors will lead to 1 of 2 things, Larger fuel pump or running dual fuel pumps, remeber the fuel rails are small, real small, and require serious grunt to keep em full!

LTDHO

Just thought I'd mention.

I had the LTD on the Dyno today, trying, amongst other things a new (bigger) MAF.

It made an extra 2 kw at 5200.

That's it. Nothing else. It also ran at a dangerous 14.4 AFR.

now I could probably fix this problem with a re-calibrated chip, but how much more power should I expect?

As a matter of intrest the feul pressure in the lines after the reg is 45.

Isn't 14:7 stoichometric ??? German for perfect or ideal {bosch}
14:7 of air mass to support complete combustion
of 1 part fuel .. 14:7 to 1 so the higher the number the leaner it is.. A.P take note .. me too !!

I.M.H.O Not until you replace the inlet the std H.O won't move enough air to lean out "too" bad..When you see them side by side you can realy see the difference.There is heaps!!..

Drillout the whole in you'r butterfly alittle and I'll guarantee the idle come's good.. You are replacing it soon anyway.. hth Kelli..

I was told it should be abut 12.7?
I am running the GT40 manifolds and a bigger T/B!

Too be honest, I'm a little confused. Since I went bigger everything, naturally I went bigger MAF, which didn't do anything!

It's got me buggered. The onlt thing the bigger MAF did was make it run lean.

12:7 is rich look at the thread above! I bet your eye's water when walking around back of car..

Try using the electrics from you'r old maf ??? What maf did you get??

Are you using long tube extractors? The hego sencers may not be getting hot enough to work..
