Why You Need to Mod & Tune Your CTS-V

hey guys this is Josh from tuning school today we are going to talk about the differences between the CTSV generations there are strengths weaknesses and the differences between tuning them the Cadillac cts-v has been produced in Michigan at the Lansing plant For the past 15 years, it is an outstanding sporty luxury platform featuring a V8-powered, rear-wheel-drive configuration with manual and sometimes automatic transmission. The gen1 cts-v comes with a 2004 to 2005 model year LS6 and a 2006 to 2007 year LS2. each is controlled by a different PCM, earlier model years are controlled by a p 59 and later model years of models are driven by an e 67 the strength of this is the fact that it's naturally aspirated it's a very strong engine the other strengths that it has has that it only came on a model that's a four door with a manual there's plenty of parts on the market for it the other weakness it has would be that it has a six lug pattern for all w heels so its very hard to find an aftermarket wheel for it as well as the rear ends they are made of papier mache, what i recommend doing in that case is call GeForce Performance Engineering, they have a 9 inch IRS kit you can get for around 4500 bucks. that really completes the car the second generation cts-v features the lsa engine although it was built in mexico it is known as a staple of the american platform LS features a 1.9 liter T vs supercharger plus the strength of this is the fact that not only is it supercharged, but there are plenty of aftermarket performance parts like Metco Motorsports that make their pulley kits that can increase horsepower exponentially for relatively decent cost when it comes to the CTSV platform's weaknesses, the styling of the bodywork is in three different ways.

A coupe, it's a sedan and it's a truck, the problem is that coupe and sedan models have fallen relatively low on the scale that they used to be bought for around 65,000 per year. and the wagon has stayed up in the forty to sixty five thousand dollar range the other weakness the CTSV has is due to the supercharger actually what happens is it develops a lot of heat inside the supercharger cover , causing the intercooler to get blocked. an air to water cooling system fails what ends up happening is the end tank collapses into the intercooler block causing the system to fail causing the engine to suck cooling when recommended, in this case exhibiting a call Call on Pro Speed ​​Auto Sports to get

your

Stuart EMP pump and heat exchanger system upgrade as well as call them or dedicated motorsports to modify

your

intercooler brick to handle that extra pressure and extra heat and last but not less important there is the 3rd generation cts-v which features the LT 4 engine out of the C 7006 and even shares the same 92 computer the best part of this is the fact that the PowerPoint LT 4 is very powerful they combined it with An 8 speed automatic now what this means is there are no manuals for this year's model and sadly it only came out in a sedan.

I really wanted to see maybe a wagon option but GM decided to keep it close to the hood on this one the main flaw with the LT 4 has to be the cooling system in relation to the supercharger what ends up happening is that given which is over cranked from the factory you get ridiculously high intake air temps as well as when you try to cool the engine from this point of hot air you end up causing a charge on your coolant and oil system what I recommend you do is contact Pro Street Auto Sports and get the oil cooler setup that will help eliminate the problem on that side the other problem with an LT 4 means it is direct injection and as we all know direct injection isn't really what which we thought it would be, it's great for fuel economy and it's really good by EPA standards, but when it comes to generating power, it leaves a bit on the table what term What's happening is you run out of a low side system which would be your in-tank fuel pump and then you run out of a high side system which would be the high pressure fuel pump inside the engine for direct injection capabilities what What I recommend you do is go up to Quarters Performance and get a low side fuel system kit and call Brian Cooley and get a 38% larger fuel lobe on the cam to take care of your overall high pressure fuel pump , the CTSV has performed outstanding in the sedan market has done well at the Nurburgring has done well in quarter and zero to sixty times and always ranks well in car magazine comparisons unfortunately as of close of 2019 Cadillac decided to discontinue the CTS B model and move on to the CT 5 we are interested here at tuning school to see what the CT 5 has to offer and its capabilities tuning and in your power plant now when it comes to tuning this is where they separate very differently the Gen one cts-v is like I said function for PCM so you have your p 59 and then you have your East 67th the problem with the first gen e 67 is that it has a high and low math curve what that means is now i have to split my curve in half and match the values ​​which i think are 5800 Hertz in order to make the vehicle run smoothly not a big deal but can be a pain if it doesn't match those old models P59 ecu values ​​may be a little slower for some

tune

rs but with a little patience you will be very successful , generation 2 cts-v features the same East 67 computer but this time instead of dividing the math curve into a high and a low they decided to make it back into a single table it has a lot of resolution which makes it very easy to

tune

uses When the airflow based system also features a build pressure system control module what this means is the boost increases due to the LSA supercharger which will try to compensate by actually adding fuel pressure you can get the license from this and modify this file inside the tune.

Gen 3 cts-v is where the Gen 5 platform comes in. I recommend you contact us and get our Gen 5 book as there is a lot of information that differs from the Gen 1 and 2 platforms as they were based on the airflow and Gen 5 platforms are charge based.
