Im gonna play with this when I get home this afternoon!

What does the VE and VQ map adjust mean?

I too am having start issues with my rb25, ford lightning maf in 4 inch intake tube. When cold it starts at like 30. When it goes to the next cell I usually cut the car off and try again. 30 starts it up all the way to like 170degrees Fahrenheit. After that she wont start. Pulled the plugs and they ...

Im running mine in a 4 inch tube. Rb25det,built bottom end with 1000cc with a honda accord v6 resistor box wired inline. I wanna say that my latency is at 760 from the start. Did u increase it? And when you hold the revs at idle would the afr look ok? I have to increase the min ttp. And even then it...

any updates?

Are you using 2.5 pvc b/c you had it laying around? Im mean If I'm gonna have to set this hpx up as draw through then it will be fitted into a 4 inch pipe...smallest being a 3.5 since the software supports that.

use a diablo maf extended and new lightning MAF or bite the bullet and get a speed density system installed. You won't be disappointed, either way, just out of pocket. If you still experience the same issues then the problem will be more obvious. Yeah I was looking into that. The prices seem to be ...

So putting the lightning maf in a 4 inch tube setup as draw through should support 500+ hp?

Ok. Currently my car is sitting at the shop and Im debating what I can do with this sensor and program. I really don't want to fork out anouther 2 grand on an AEM or Haltech unit...thats last resort if I can use what I have.

Try a Z32 maf or the IPX maf. Or do what I did and buy a AEM lol. Im trying not to buy a 1500 dollar ecu program but with the money wasted on this junk I should have....I feel like a test dummy with this maf junk. I dont wanna reduce the intake from 4 inch to a small dildo z32 maf. It just looks re...

Understand with the HPX that the calibration curves originally came by doubling the existing tables values but were not accurate enough so I could never get it running on the R31 Now since the VMP calculations were hacked I am able to put the better calibration curves in now but testing takes time ...

If a maf is maxing out on blow through and I swicth it to draw through would it be completly different as far as how much power it will support? I was maxing out my ford lightning maf when installed in the tube and im considering relocating before the turbo on the inlet.....tuner said it wont make ...

Update: took my car to a reputable tuner that has been playing with nistune for 6 years now. He talks good about this program but just like me he didn't feel comfortable putting it on the dyno. He actually used my exact words "It was acting stupid," and Wasn't reacting like it was suppose ...

Its a rb25det bored. 040 over with a set of wiseco's. Ring gap is set for turbo street/strip. Stock valves with a 5 angle valve job. I dont think its the engine since all I did was removed the cold pipe, and have the welder remove and add in a 12 inch piece where the old map was located. I even did ...

I changed the vq. Look at the attachment. The afrs are all over the place at idle and there is a blip at idle. If you would like I could make a video. Like I said...before this hpx I had the frod lightning maf and it was fairly easy to tune. I even tuned the lightning maf with my old turbo setup wit...
