Anyone got any info on speedo tuning??

Hi gents, possible already been covered but here goes.I put a th400 in so for my speedo i moved the originl speed sensor from the 4l60e to the rear abs reluctor.in my pcm i changed the tooth count...

Hi gents got a question about my 02 voltage when im in boost.when for a lap and when i was in boost the 02 voltage was fine then went to like 50mv and my wideband went full lean under boost.i know i...

All good mate... I have still have had no luck tho making the EGR channel into a maths parameter that will read in the chart vs time.....i can get it to read the volts fine like in the channels list...

I do have a aem wideband????the sensor is for fuel pressure not to sure how a aem wideband is going to help.

Thanks for the reply gents.The sensor is a 0-100psi 0.5-4.5 linear voltage output.its just a ebay special but seems to work fine if i use one of the ports on the mpvi pro and set it up that way.just...

HI hoping someone might be able to help me with the user defined function.I want to log fuel pressure through the EGR port on the pcm. I added egr sensor voltage as a channel then went to Tools,Maths...

Any one???

Yeah would be good to log fuel pressure and exhaust back pressure.hope someone can help..

Hi guys looking to set up an oil pressure sensor through the mpvi pro 2nd input on the side.i have added the input to my channels list and have gone to transform, then user defined.i put the...

my question has possible already been answered but, in channels i have intake manifold absolute pressure (SAE) , and manifold absolute pressure - 3 bar and map in chart vs time.my question is why do...

NOT really tuning realated but does anyone know the differences in the ls2 block to the l98???I cant find the l98 block specs....... wanting to know will the internals out of a ls2 fit in a l98...

Didnt Know where to post my qustion anyway
yes you did answer my question thanks But i dont know how i would set my wideband to read eq ratio error??? I have a aem 30-4110 and used the pre defined...

Hi guys, Starting to tune boost with my wideband and have set up a EQ Ratio Error (MATH) Graph of my 3bar VE table and the data is looking good but my question is the Equivalency ratio commanded AFR,...

Oh ok when i changed the map offsets i done a log of the stock map sensor at idle and engine off and then done one with the 3 bar idle and engine off they seamed to have the same readings.I got those...

Its A 3.3bar map sensor

Hi Guys, Just having a issue when i blimp or stab the throttle when cold it dyes down before revving up. Its 3 bar sd tune ls3 injectors cam all the usual stuff.My timing seems to dye down before...

Sweet as good to know tho.just happend to me when i went 3 bar sd and didnt fit the 3 bar map sensor.good luck with your build.

Only reason i ask is because if you havnt changed the offsets values it could cause this.

Have you changed the map sensor???

SO i did decide to start again and have finally had success.I used the compare function to make everything i had done the same on the new tune and by surprise the IAC is not going to 0 anymore.all...
