No there is no map etc..For what its worth to make it work will cost you more than a maf. Whats wrong with your maf? Too small? Well buy a new one or bigger one from www.capa.com.au or the U.S either www.summitracing.com or www.jegs.com or if you ask Lunatic svt.. nicely he may help you out...
With out maf it will run rich and any mods you may do won't run properly.. Pete I bet will add heaps more...

If there's commotion coming from the passenger seat, and nothing but earth going round and round outside the windows,.......then everything is not as it seems!
The only time you have too much fuel, is when you're on fire!
I have seen an NF stock 5.0L that had the MAF unplugged for weeks, as it was done accidentally by a mechanic that serviced it; the owner only noticed it had a slight hesitation sometimes and a few other glitches.
It idled perfect and if rpm was progressively increased you wouldn’t have noticed a thing.
EBXR8240 is big enough proof 5.0L's can run without them, just it is not advised, especially when engine is not stock. :s5

No wanting to steal this thread, but I am interested in this subject too!
Early truck 5.0L's only used a map sensor and no MAF, but the problem with their injection setup is it is only bank injection not sequential injection.
The real question is, early EB 5.0L's used both MAP and MAF, can their ECU be modded to do without MAF, it would save a lot of piss farting around setting up twin MAF and save shit loads of money, not to mention being pissed that you chose the wrong size because of cost.
Yes I know EBXR8240 has had a thread talking about it, but I couldn’t find it. :s5
Closed loop will work anyway because of TPS, MAP, air temp and O2 sensor, just not as refined and most likely not as responsive. (Basically EA/AU I6 setup)
Pete you can tell us why not again for the umteenth time. :s6:

Well that article is pretty good...it tells you why.
Early EB 5.0's had BAP not MAP. Barometric compensation was deemed to be well accounted for by the MAF so it was abandoned after EB 1.
The engine will run without MAF but it will run badly. If it has no MAF it cannot sense load or air mass therefore it cannot get the fuel or spark right. The reason it will run is that the EEC has a MAF failure map that will basically give something like limp mode fueling. Closed loop will not occur in MAF failure mode.
Did eb240 tell you how bad it ran? He told me....Terrible is one word for it.
Two MAF's is still cheaper than aftermarket engine management.
