![]() It opens to remove exhaust pressure pre turbo, and closes to add more in order to achieve a target amount of boost. Your wastegate acts as a regulator for boost. For example between intake runners rather than at the back of the intake manifold where air does not flow past. These sensors need to go post intercooler and should be in a place that is representative of the air going in the intake runner. These can be found HERE in a variety of sizes and plug styles. As a little bit of a plug, we sell a fast response sensor that is 15x faster and 3x more accurate. This is concerning and can cause many issues. This means that your engine may have intake air temperatures much higher than the sensor is reading, and your efi system is tuning to that wrong info. Factory Style IAT sensors as commonly used by big name EFI companies and sold by many retailers are SLOW response. This one is often overlooked but needs to be there, be a good fast response sensor, and needs to be in the correct location. Note these are different than a factory style Narrowband sensor. This is essential as a reference for your ECU to operate off of for aftermarket ECU and as a reference for even factory style ECU that your tuner will tune off of. ![]() Again do not put too large of a sensor compared to what you need as it reduces resolution and the ecu ability to react to small changes. For this reason you will need a 3 bar minimum sensor which reads to 29 psi, 4 bar reads to 43.5 psi, 5 bar reads to 58 psi. This is of course not sufficient for boost. Factory cars that are not built with forced induction come equipped with a 1 bar map sensor which essentially measures vacuum up to a ceiling or ambient atmospheric pressure (no boost). This lets your ECU know where in the table fueling needs to be. This sensor monitors the vacuum and also positive (boost) pressure in your intake manifold. Keep in mind you do not want to go way too large on the sensor as the greater the max pressure of the sensor the lower the resolution is. So if you are starting at 85 psi and adding 30 psi, you need a 115 so a 150psi sensor would be best. However, with some injectors and tuning styles base pressure may start much higher in order to maximize a fuel injector, etc. You want to leave some wiggle room for growth an extreme instances. If I am running 30 psi of boost I need atleast a 73.5 lb worth of fuel pressure sensor. For instance 43.5 lb is a very common base pressure. This can easily be figured out by adding your base fuel pressure to the amount of boost you want to run. Typically this sensor needs to be 100 or 150psi. This means that for every pound of boost, the fuel pressure regulator adds a pound of fuel pressure to overcome the boost in the intake in delivering enough fuel. ![]() Please note this list doesn't mention standard engine sensors such as coolant, oil pressure, tps, iac, etc as they are needed on any EFI engine.īoosted applications utilize a boost reference style fuel system. So we went ahead and put together the basics and then some "would be nice" below. Lets face it, you don't do this for a living and the internet can be a very cloudy place for information. With the rapid growth of forced induction and technology that goes along with it, the sensors and what is actually needed can be quite daunting. ![]() These coils came factory on most 2005 + GM based vehicles with the LS based engines.So this is your first EFI setup? Or first turbocharged combination. These brackets can be mounted on the frame rails, firewall, under the headers on each side, etc. We include two 24" relocation harnesses that allow you to mount the coil pack anywhere you want. The hardware consists of four 1/4" through bolts and poly lock nuts, and 12 billet aluminum spacers. This kit contains two brackets and enough hardware to do 8 coils or one V8 engine. Consisting of two laser cut cage type brackets that have been powder coated gloss black. This is a bolt on LS coil relocation kit. With coils mounted they are approximately 6"x4.25"x2.25" Laser Cut and Powder Coated Black Bracketģ6" Relocation Harness Included (allows for relocation to about anywhere) (24" available upon request)Ģ Brackets, 2 Coil Harnesses, and two Extension Harnesses Includedīrackets are 6"x3.5"x1.25". 475 Thickness where it bolts to the bracket (12573190, D514A, etc) Coil Pack Relocation Kit - Brackets, Coil Harness, and 36" extension harnessįits LS3 LS4 LS9 LSX Coils with the following coil numbers 12570616, 12611424, D510C ![]()
