So I've done a bit of digging and got myself familiar with the parts needed to supercharge my LAP motor. One thing I don't get is the tuning procedure after all the parts are installed. I'd like to do the work myself so can anybody point me in the right direction?

rico

i got a full sc set up i need to sell . let me know if interested pm me

I'm not spending a single penny on this until I can understand the entire procedure from start to finish 100%.

what are you confused about? you buy everything the ss/sc has bolted to the short block basically and put it on yours then get a tune from vince at trifecta performance and you have a supercharged cobalt lol. I mean yeah there's some grinding you will need to do to the eterior of your cylinder head to make it all bolt on but it's a cake walk and can be done in a weekend if not a day. The hard part is finding all the parts you need for this but there's plenty of 2.2 supercharged threads, and plenty of parts lists so if you just search you should be good for a guideline.

You can definately utilize Trifecta tuning. Essentially, they create a base tune for you, email it to you so you can download it into a device. You upload that into your car via the device you rent from them. I know there is a cable you can buy but I haven't looked into it. When it comes down to it, you get a base tune, then they work with you via email/phone to refine it. You might be able to use LS2 Edit. Today at this point in time ls2e would allow you to do tuning.. If you can use it - I don't know much about this either as I have an 06 l61. In the future you may have an option from Trifecta to do the tuning your self but as it stands today, you get it from them.

Thanks n00b

Just wondering, is there anyway to tune the car yourself after everything has been bolted on, on a dyno with a laptop?

Cobaltsky05

I thought HP tuners could tune the l61 ecu's... I will email them and find out but for the price I am happy with my tune from vince at trifecta.

I was just letting the individual know. just incase they found the info they needed and were interested.. sorry?

cobalt123

hptuners cannot do the 2.2 l61s they just came out to do the newer laps only they are not gonna be available for the l61 at all trifecta is yours and my only option

or you could ask us folks who have dedicated the last 3 years to researching stuff like this

LTBALTBMX

Uhh guys I have an LAP engine, not L61. I will look into HP Tuners. Is there a guide for it?

As far as the tuning, I've done the first LAP supercharged so Vince @ Trifecta Performance already has a base LAP tune. You contact him, pay the $250, and then he will send you a base tune. You then data log and he will tweak the tune and send back.

As far as the whole LAP supercharged thing, I have it all laid out in my LAP supercharged thread here.

https://www.cobaltss.net/forums/2-2l-lap-performance-tech-168/genes-2-2-lap-supercharger-build-166563/

I have compiled a parts list for the 2.2's and mine was especially made up for the LAP.

Good luck.

This list is broken down to bare essentials for supercharging only and then adds the optional exhaust and optional wiper conversion lists. What type of injectors, pulley’s and other items you choose to change are strictly up to you. This is the list that I used and have modified it for a universal parts list.

Purchasing the LSJ power brake booster hose takes care of 2 issues. I cut off the ends of my 2.2 hose and used it as a PCV hose from the valve cover to the LSJ air intake hose. It gives you the correct hose from your power brake booster to SC and gives you a factory looking formed hose for your PCV hose.

Injector Harness

I used the 2005 Cavalier injector wiring harness because it came with the proper connectors for using the original GM 42.5 lb Stage 2 injectors. I did have to splice my MAP sensor connector in from my original harness as I started out with the stock MAP sensor.

MAP Sensor

You can choose to use 3 different MAP sensors for your conversion. Which MAP sensor you choose will also depend on the connector needed to be used.

Stock MAP
This MAP sensor fits into the LSJ intake manifold, but you must modify the opening in the sensor where it screws into the intake. How I modified the sensor is in my SC build thread. This is the least expensive option and is the least hassle option.

LSJ 1 Bar MAP
This is the MAP sensor that is used in the SC on the stock LSJ. We can take that sensor and use it in the LSJ intake manifold. You will need to modify a means to secure it and also seal it to the LSJ intake manifold. How I modified this sensor to fit my car is also in my SC build thread. I would honestly say this is the least optimal choice out of the 3 possibilities for me.

LSJ 2.5 Bar MAP
This is the real MAP sensor used on the stock LSJ in the intake manifold. It best fits the stock LSJ intake manifold (obviously). This MAP sensor also has a temp sensor, otherwise known as IAT2 (Intake Air Temperature 2). Our cars cannot read the temp without modification. How I did the 2.5 bar MAP sensor conversion to read IAT2’s is also in my SC build thread.

Throttle Body Connector

If you are using the LSJ throttle body the connector you’ll need to have is an 8 pin. Regardless of what connector you do have or if you have to purchase the 8 pin, you will need to wire them for the LSJ TB.

2005 – 2006 2.2’s have an 8 pin connector. No new connector is needed.
2007+ 2.2’s have a 6 pin connector and you will need the 8 pin connector.

2006 – 2007 2.4’s have an 8 pin connector. No new connector is needed.
2008+ 2.4’s have a 6 pin connector and you will need the 8 pin connector.

If you need the 8 pin connector you’ll need the one below.

Supercharger Cooling System

New GM Parts

22697069 – LSC SC Coolant Reservoir
15076936 – LSJ SC Coolant Reservoir Cap
15271970 – LSJ SC Coolant Reservoir Bracket
22697111 – LSJ SC Coolant Reservoir Overflow Hose
22699879 – LSJ SC Coolant Reservoir Inlet To Top Intake Manifold End Plate Hose
22707607 – LSJ Bottom Intake Manifold End Plate To Intercooler Pump Outlet Hose

Hose routing is with using ZZP heat exchanger only with 10 feet of ž heater hose. The house routing diagram I used is in my SC build thread.

First hose went from LSJ SC coolant reservoir outlet to ZZP heat exchanger inlet.
Second hose went from intercooler pump inlet to ZZP heat exchanger outlet.

I chose the stock SC cooling system for now. If you choose to use option B or any other alternative then you will need different hoses and lengths of hose.

I am running a 2.9 pulley with the ZZP heat exchanger only and my IAT2 temps are within +20 to +30 above ambient temp (which is optimal). Of course in traffic or during heavy WOT runs the temps are higher as expected (which is normal). This cooling method is very adequate.

Exhaust Parts (Optional)

GM Parts

90537953 – LSJ Exhaust Manifold Heat Shield
15231157 – LSJ Downpipe To Cat Back Gasket
15235773 – LSJ Exhaust Manifold To Downpipe Gasket

Use your stock 2.2 or 2.4 exhaust manifold gasket, or buy new, as if you used the LSJ exhaust manifold gasket it wouldn’t fit properly and you would have an exhaust leak and/or noise.

Used Parts

Stock LSJ Downpipe
Stock LSJ Exhaust Manifold

The stock LSJ downpipe works on any manual shift car. It does not fit the automatic because of the way the automatic engine sits in the vehicle.

The LSJ exhaust manifold and LSJ downpipe are much bigger to allow more exhaust to exit the engine. This is important as you are forcing more air into the engine with the supercharger so you need to provide adequate output as well. Feel free to purchase your aftermarket selection of header/dp combo.

Windshield Wiper Conversion (Optional)

GM Parts

22729469 – LSJ Windshield Washer Container
22732432 – LSJ Wiper Cowl To Washer Container Hose

You’re moving the LSJ air intake to the left side of the vehicle and that is where the 2.2 and 2.4 windshield wiper container is. The container I listed includes a new pump, grommet, cap and hose to attach to wiper cowl hose. The wiper cowl to container hose I list is the original GM hose on the LSJ that goes from the left side of the wiper cowl (where ours is) and takes it to the right side where it meets up with the LSJ washer container that I list. As far as the connector for the pump, I cut the end of the connector off and added new wire to loom it from the left side of the car to the right side of the car to the new container location. I ran the loom across the top of the inside of the radiator support where there is already a loom running for something else. I ran it inside its own loom and wire tired to the existing loom.

Wow Gene! Thanks for the early Christmas present! You are an asset to this board! Thank you so much.

I guess I'm going to forget about tuning myself as it looks like its a huge pain in the ___. I'll let trifecta take care of it. Now to start collecting the parts .

No problem, you're welcome. You don't really want to get into the tuning unless you know 100% what you're doing. For the price, I leave it up to Vince.

rico

collect parts. nehh. i have almost pretty much a full kit for sale:p

jschatte

go info in this thread. the tuning is what scares me the most about doing a upgrade like this

Gene Culley

iTrader: (1)

Honestly, tuning is the last thing to worry about as it was pretty easy for me. I just give Vince the logs and feedback on what is going on and it is handled properly by him.

jschatte

so what your saying is you would request a tune from trifecta just to get your car operational, then you would run it for a bit and get a log (not sure how this would be obtained) and send it back. then vince would look at parameters that need to be adjusted and send you a new tune?

Gene Culley

iTrader: (1)

Yes, for example.

You pay for the tune. You send Vince your VIN and what your mods are.

Here is what I emailed Vince the first time.

2.2 LAP Engine.
GM Stage 2 (42.5lb) Injectors
3.0 Pulley
LSJ Header
LSJ DP
LSJ 1 Bar Map Sensor
LSJ Throttle Body

Want to remove speed limiter.
Should I do anything with the rev limiter?

Removing SAI.

Then he sent me a tune, basically a guess of the parameters I would need. I started the car, didn't drive it and then sent him the logs. He said everything looked good enough to drive. Then I drove it and logged it and then he said this needs changed, that needs changed and he sent me a new tune. I data logged, etc, sent it back. He said we're looking better and he changed this or that. By the time Vince says he is happy with what he sees in the logs the car is just about perfect.

But you do have to give him your feedback here and there.

It is extremely easy to do.

jschatte

well that seems like a pretty good system. is there alot of initial downtime for your car? I take it this is done thru e-mail. How do you apply the tune?

Gene Culley

iTrader: (1)

I ordered the tune like 3 weeks before my planned project because I thought it would take a long time. In about a week, I had the cable at my house (for the laptop) and Vince had emailed me with the initial tune. So 2 weeks prior I was ready for the car to be fired up and I didn't have to worry about it.

Sometimes, in between adjustments, it may take him a day or two to get back to you, but 99% of the time it is a slight adjustment that you can drive you car for without damaging anything.
