In short, a timing calculator is a spreadsheet or piece of software that can be used to automatically generate new injection timing values based on the changes that you've made to injection pulse width. The injection timing on the Z28 is injecting right around mid overlap of the cam at idle To my understanding via the spreadsheet the rpm and ect tables are both adders not subtractors - In other words it moves the soi sooner. 2010 Vette Stock Bottom LS3 - LS2 APS Twin Turbo Kit, Trick Flow Heads and Custom Cam - 12psi - 714rwhp and 820rwtq / 100hp Nitrous Shot starting at 3000 I have played around with the EOIT boundary to reduce or remove the raw fuel mixture being sent out the exhaust valve with my new cam (has 8* overlap). 11 gears Cam is a TSP version of the BTR Racing Stage IV turbo Duration @ .

They said if your injectors are big enough and you can supply the amount of fuel necessary to get the injector timing close to peak piston velocity. If the file you want to pull data from is a late, post-'09 file, do not use the injector conversion spreadsheet. Then paste that data into your tune. The difference could be in AFR. First here are some links to excel spreadsheet calculators circulating on HPtuners forum for injector timing. - In the diesel tuning aftermarket, timing calculators are often used to help tuners speed up the process of adjusting injection timing maps.

VE table is spot on as dialed in by WB and all injector values are taken from the Holden Injection Event Timing Calculator The stock PCM values are already entered for boundary, normal ETC, RPM advance and the stock cam IVO, you can to enter what ever your value for IPW, it will high light in green when injection is on a closed inlet valve, red when the inlet valve is open, black when either the start or the end of the boundary is met. This doesnt work well with a cam like yours with that much overlap. They need to be direct replacement that will physically replace the current OEM LS3 injectors without any additional Gen 5 injection timing is real simple and can be overly complicated rather easily Other than the exhaust - forget about valve events Your goal as simply as it can be put is to optimize timing enough to where the fuel is burning cleaner which is usually during higher cylinder pressure injections, but to not inject so late that it causes false knock from the injection window If that’s the case moving injector timing shortening the pulse I think would put the pressure back up and might be a balance to be found and find a little more from this setup stock. View Profile View Forum Posts Private Message Senior Tuner Join Date Mar 2007 Location Hopefully somebody can look this injector timing spreadsheet over and give me some pointers.

We've come to understand that each period is 90 degrees of crank rotation, so adding . You only adjustment is to move SOI sooner or later and EOI will follow. Stock ls IT you will be spraying the injector and lose a lot of fuel out the Injectors will control inj timing more than the cam - overly large inj will require advanced almost always.

Before you do any major changes to the idle airflow or idle timing you really need to fix the MAF curve and VE table so that fueling is corrected for the new camshaft. My question is, how accurate is the spreadsheet? the car definitely feels better and im hoping that ive not adjusted things too much. That's a big difference to me. The value you get goes into both makeup and boundary tables. For instance stock In those injector data sheets, you use the appropriate multiplier for the current fuel pressure out of the 4 comp tables on the right side, multiply both slopes, breakpoint, and voltage offset by those to get the appropriate values. Dont forget the car has variable valve timing and spark adders as well so it stands to reason the injection timing will also coincide. 60 LB 95 LB.

There will be video just like the LNF but be patient as i have to refresh myself on the LSJ platform and will most likely be colaborating between other members to ensure i do not make a video with steps that cause For the stock parameters, an injector duty cycle larger than 75% pushes the start of the injector time prior to the 0.
