90mm SCT MAF sensor

[exploder97]

Ok so I just went out to Kurgan Motorsports today and picked up the SCT Big Air 90mm MAF for the truck, I have to weld in a 02 sensor bung so that we can do some Wide Band O2 for the tuning with this but i will be writing up a how to if you will on the entire process as well as some pictures, let me tell you though this thing is WAY bigger than stock, if im not mistaken stock is somewhere around 60 or so mm. Talking with Bob he said that i should be able to see a pretty good increase in throttle response as well as HP. The MAF is rated up to 700hp so should be a good setup.

He told me hes used these before in Mustangs but has never used one in the Explorer Application, so im somewhat of a guinee pig for this. Here is a Picture of what it is, the best part is that its a non calibrated so with tuning via the chip it will be compatible with any injector setup.

If anyone has question or maybe want to be the next inline to do this let me know ill get you intouch with him.

Heres a pic to tide you all over

I got to know what you are up to here.
Sounds like a good maf, I'm espesially interested in tuning it on car, rather than being pre calibrated.
Keep me posted

What is your reasoning with selecting such a large MAF?

Thanks ......

The TB is only going to allow so much of that amount of air through, it seems to me.

Let us know how things go.

Very good meter. Lots of guys on the Lightning board run them, or either the MAFia extender. The extender allows you to raise the voltage of the stock meter so it doesn't peg out.

What are you up to if it's rated that high???

I agree; well known fact; although the Big A MAF is a great tuner item, I doubt that it would be helpful in a NA set-up- even with nitrous. Mainly a forced induction item; but will likely work just fine on your vehicle.

Hello all..

We are taking baby steps with Chris's truck.... eventually it will be blown, so we are putting all the parts together that we will need when the blower is eventually put on. The reason that the BA-2400 meter was selected was for the quality of the calibration. These meters are electronically calibrated by HITACHI, a multi million dollar company. They are not calibrated for any particular injector size as I do that through the chip. When Chris gets larger injectors and the blower, i can go into the SCT software and select his injector and 90% of the work will be done. A larger throttle is in the works along with other things. If you have any more questions, feel free to visit my site or shoot me an email.

thanks !

Now the picture is more clear; I'm real excited to see the future outcome and will definitely be visiting your site for more information. Your sig. certainly confirms your abilities and experience. Rock on!

thanks for your vote of confidence..

I have been tuning mustangs and high performance cars for about 10yrs... I never really thought about getting involved with trucks etc... Chris brought it to my attention that there are people in this market that want to go fast and make more power.. I dont want to step on ANY TOES on this board, so if you or anyone has questions, feel free to email me etc.

thanks bob

Yeah there is a pretty big market here. A lot of sceptics too so be ready .

I look forward to the information you provide.

 

[spindlecone]

More info pls as said above

 

[Bob Kurgan]

does anyone know who i need to PM or email regarding advertising on the site?

You think there are alot of skeptics here?? Try the mustang market hahahah

feel free to visit my website and click on testimonials... Most of them were skeptics at 1 time or another!!!

BTW, I dynoed my first ranger yesterday (saturday)... it was a 2002 with a 4.0 (auto) with cai and exhaust... the baseline was 179rwhp and 204rwtq... i tuned it with 87octane (thats what he had in it) and it made 202rwhp and 230rwtq.... the gains were AT LEAST 20rwhp and 25rwtq THROUGHOUT the ENTIRE curve.. i was pretty excited!

 

[spindlecone]

Bob
Great numbers, did you measure the guys A/F ratio also?

 

[Bob Kurgan]

no, we made 202 with computer tuning on 87 octane..

yes, i did record a/f.... prior to chip'n the ranger, the a/f was 13.2 at the beginning of the run and tapered off to 12.0 at the top of the pass... after i played with the timing tables and MAF transfer function, it was 13.0 all the way from 2500 to 5400rpm (low compression motors i run about 13.0 to 1 as opposed to higher compression NA motors at 12.5-12.8)... I can get a dyno graph to post if you guys would like.. Also, these are SAE dyno numbers, not the inflated STD numbers!

Wow, that's good considering the 87 program doesn't add any timing. Of course with numbers starting off near 180 that doesn't surprize me from that dyno.

As for using the BA2400 with a 4.0 even in supercharged format it is too large and just overkill. Yes, it's a great meter but not for the amount of airflow the 4.0 makes down low. Yes, it will be fine at WOT but under normal driving conditions and at idle then you may have some resolution issues.

Hi Bob, this is Doug with BamaChips, I've been doing the 4.0 trucks for alot time now and if you have any questions about supercharging them feel free to shoot me an email BamaChips@gmail.com.

Thanks, Doug.

Hi Doug..

thanks for the offer.. you are correct, the base 87 SCT doesnt add much timing.. I went and modified the timing tables to something closer to the base 91 tune and experienced zero knock... as you know, the stock program was around 15degrees and I ended up around 19degrees (91octane program was 21ish)... I didnt state that I made 20rwhp more with the 87 octane SCT tune, i stated that I made 20rwhp more with 87 octane fuel and thats what it did (again, with no spark knock).. I tried 21.5 degrees and it knocked...

as for the SCT BA-2400 and low HP vehicles, the resolution down low is great.. I have used it about 30 times on EEC IV mustangs and EEC V mustangs that are only making 300rwhp or so... they idle better then stock and are very repeatable.


thanks bob

darn doug, i just reread this.. I have ZERO intentions of running an SCT BA2400 on a 4.0.... this thread was based on a 97 explorer with a 5.0 pushrod motor in it... hope that clarifys that for you!

thanks bob

doug, i dont know if this was a shot at me but it looks as tho my baseline pull at 180 (actually 179) was very close to the baseline pull of 181 off your site for one of your customers... you started with 181 and ended with 186 and the avg numbers dont look like they improved a ton... here is off your site

i am working on getting the dyno sheet for the ranger i did yesterday... as i said, it baselined at 180ish and ended up at 202 and the avg numbers increased the same amount..

thanks bob

 

[Doug904]

No, not a shot but just the fact that it was making 180 rwhp to begin from is rather high for a stock 4.0, even with intake and an exhaust. I've seen those numbers but not very often. That is great that it took that kinda timing figures though, what kind of outside temps were you at? On the 4.0's I've dynoed, in the South or in California, don't take much timing over stock with 87 octane. Now through some 89 in it and it will handle more. 202 rwhp is definatly a noteworthy gain on a Ranger and I'm glad that you've seen this amount as well as I as you'll find out here there are alot of naysayers.

thanks, Doug.
