In this blog, we are going to discuss the different areas of our initial tuning forms.
NA or Power Adder Tune?
NA is naturally aspirated. No nitrous or turbo, etc.
Power Adder- This means you have nitrous, turbo, and supercharger on the vehicle.
Will you be doing 93 octane and running E85 also? You will start with your normal gas (87-93) tunes and email data logs and make all revisions in 100% gas to start. Once all gas data logs are complete, we enable and work on E85 data logging. Must have a flex fuel sensor installed.
Swap- you have swapped an LS/LT engine in a vehicle that didn't come with it. Be it an older car or one that you removed a V6 and put in a V8
Street- the vehicle is used as a daily driver, back and forth to work and occasion track visits.
Race- the vehicle is used for mainly the track. You use the vehicle for racing.
Does your VIN match?
We understand with a swap that the vehicle and PCM will not match. But with non-swaps and 07 up they must match. If they do not you will run into issues with vehicle security.
Does your engine, PCM, and vehicle match?
Your vehicle engine PCM must match. That means you have a V8 LS engine that is driven by a wire-throttle body. You must have a V8 drive wire PCM. Gen 3 engine and Gen 3 PCM. You cannot run your v8 swap with a v6 computer.
Fuel: Type and Octane Rating
What fuel will you run 87, 89, 91, 93 octane? If you selected above to run the e85 option we'll still need to know if regular octane will run normally besides e85.
If it is completely stock select that, if you have changed the pump, or anything then select aftermarket and you will then be asked to provide the following details: Specify fuel pump, return/return less, fuel regulator type, and base pressure.
If you have an aftermarket cam then select that option and give details of the cam. Part number, lift, duration, etc. The more info the better.
List what heads you are running, stock, ported, and aftermarket bigger ones. Provide details on aftermarket heads.
If it is stock select stock, but if it's not stock then provide the part number and flow rate. Do not list the calculated flow rate. Also, do not use decapped injectors, we will not tune for them.
Stock LS/LT intake manifold or are you running a FAST, MSD, etc.? Many times when changing the manifold the map sensor is changed please specify.
What throttle body are you running? Stock or aftermarket like a Nick Williams, Katech, TSP, and list size of the throttle body as well, 95mm, 102, 105mm.
Do you have long tubes, shorty headers or are they stock?
Are the stock ones after-market or non-present?
Do you have to do emissions testing where you are? All MOT tunes will pass system readiness testing
What Trans are you running? Manual, 4l80, etc.
What converter are you running in your auto car? Stock one or aftermarket. If aftermarket you are going to list your details in the box below. Specify brand, stall speed, etc. If you have a stall in 07 or newer you must send a download TCM with PCM. This is required to change for stall and even tire size.
How do you want your auto-trans to shift? Soft if more for normal daily driving cars. Medium is more geared toward occasional racing. Hard is for those hardcore racers. If you are unsure call us.
Rear-end gear ratio
What gears are in your rear end, having this off can affect shift points and speed
What tire size are you running, give details such as 305/45/17. This being off can affect shift points and speed.
Desired fan speed
This is for when your fan kicks on, helping cool the vehicle. If the thermostat has been changed to a cooler one this should be adjusted.
Yes/no? *Custom application remove Vats VATS=Vehicle Anti-Theft System (Must be removed for swaps)
