MAF/MAP Blend

[maisonmays22]

Hello, I have a few questions regarding a transition from speed density to maf system on a microsquirt ecu.
How difficult is this to pull off? I have an 88 Fox so it didnt come with factory maf sensor but i know about the kit.
What maf sensor should i use? i have 42lb injectors on a 408ci small block.
Is this worth my time to get more accurate tune/performance?

A properly tuned SD will seems just like you are running a properly tuned MAF...

You will want to run something with known curves I personally like to run the Lmaf 90mm then wire it into the MS using one of the spare ADC inputs and the signal ground [ for the maf return] knock and baro inputs work well.

Then you will need to set the tune up for the MAF I suggest running the ign table SD

I think i may go with it just to make tuning easier as i make changes in the future. So I can look up the curves for that maf pretty easy? or does it come with the sensor when i buy it. Also, when i install do i need that installation kit from LMR? or can i just direct wire it from the ecu

Direct wire it, maf tuning is not necessarily easier... still have to know what your doing. but its fun to experiment with it.

I can supply the MAF curve for the 90mm lmaf if needed.

@a91what that would be helpful. I think i will order one today.

I've been using blend for quite a while now. I noticed an immediate difference from SD only. It really depends on your setup. Seems to make a bigger difference with forced induction. Even works with the C&L housing with the factory sensor. Don't need anything expensive. I have the C&L curves for most configurations, he had the best flow bench in the country.

Blown88gt what kind of difference did you notice? I've been thinking about doing the same . Any have pro m 80mm curve sheet ?

Better throttle response, revs like a rotary, smoother idle.
You can get them from Pro-M.

I'm setting mine up this way. It was recommended to me to get your SD tune solid with the MAF hooked up for logging. Then switch to blend and clean it up.
