90mm MAF

[stevebo17]

I just bought a SLP 90mm MAF and I'm pretty sure but wanted to check... No need to change tune right?

[Russ K]

That would be a 85 mm maf, and yes you will need to tune the AFR by rescaling the maf table.

right sorry..... do I just increase the whole table by a % difference in the sizes?

[Russ K]

No, you rescale the maf using the MAF AFR error % histogram using a wideband O2 sensor.

Hmmmmm I don't think I have that histogram on my config. I hate to bother but how would I set that one up?

[Russ K]

Here you go. Just change to your brand of wideband in the table & chart display as I use the FJO Racing wideband.

thanks

when I ried it I got

This Histogram is not supported with the current loaded parameters.

If this Histogram references Tables, it is possible that the vehicle
you are connected to does not support these Tables. It is also possible
that the sensor required for the Table is not found in the loaded
parameters.

If this Histogram references Sensors, it is possible that the sensor
required is not found in the loaded parameters.

If this Histogram references PIDs, it is possible that the PID required
is not found in the loaded parameters.

You will find all of your loaded parameters located on your Table Display.
To add more parameters, right click the table display and click insert.

For example, if you have a histogram built that maps Timing Advance
and you do not have Timing Advance inserted on your Table Display,
the Histogram will not function.

Did you connect the scanner to the car? If not you may have to clear the last vehicle. Click the Tools button > options > Clear Last Used Vehicle.

It would be easier for you to remove the resistor and drop
in a truck table like from the Excel sheets I've posted here.
Although if you had a vehicle that was spot-on VE tuned
(and otherwise free of fuel and air-side errors) a validated
SLP MAF table would help a lot of people (SLP giving none).
So be sure to post it up if you go that way.

[stevebo17]

so once I get the error from the histogram then what?

[Russ K]

Then use paste special multiply % to the MAF table.

Russ Kemp

[stevebo17]

but wouldn't i still be off the error changes with tp os do I use idle?

[Russ K]

Try this config file, I set it up for your AEM wideband.

I'l give it a try thanks....

Hey the new one works great thanks.....Off to tuning.......
