When the Tuner was done with the A/F adjustments on the car it was 4 hours on the Dyno and getting hot. So we gave up for the day . We looked at the [B] map [Timing] .And we saw all positive numbers. So he said he wouldnt be comfortable making adjustment there untill we found out more about it . Does any one have a screen shot of there timing maps on the R4 software ?So we can get an idea where to start .

 

The timing map only lets you retard timing so the numbers are positive. In other words, when you see the number 6 on map B that means "take out six degrees".

Zimbo : How much timing does the stock Split Second map take out at the various RPM/boost points?

 

Just to make sure....Any place I see any number at all...its pulliing that much timing ? I know its only using a narrow band of numbers..just like the A map...THANKS...Zimbo

 

Correct. On the B map, any non-zero number you see represents the amount of timing retard for that boost-vs-rpm cell.

--Steve

 

I cannot remember--but my recollection is it's something like 1 degree under 5000 rpms, then 3 degrees from 5000 to 6000, then 5.5 above 6000. Something like that. I'm taking out a bit more than that.

Looked at the original Vortech for G35 specific kit, timimg is as follows:
1 - 5000
2 - 5500
4 - 6000
8 - 6500
10 - 7000
15 - 7500
15 - 8000
Did my Dyno runs yesterday and did not use Vortech orginal for any runs at all because it is very lean compared to Zimbo's final settings so we started with his and only had to do some minor adjustments in a few spots on map A. Did not make any changes to map B. Pull #5 was our best tried another 9 after that and ended up going back to #5. Ended up with 341.4 HP at 6990 RPM. With a peak torque of 286 lb-ft at 4985 RPM. Curve is very smooth from top to bottom. All pulls ended up being done in 3rd gear, could not do 4th as at the top end his dyno started doing some crazy things when we neared 140MPH. The car is a G35 sedan 5 AT.

 

Was that done on a Mustang Dyno ? I got the same #...338whp and 283torq. He said on a Dyno Jet it would come out 379whp and 312 torq.

 

why are the 350Z putting out such higher numbers than the G's?........I am at 340rwhp with no tuning done at all blowing low 10:1 A/F.........just curious

 

Thats why I asked 2003g35 what he dynoed on . Every one uses a Dyno Jet here so I ask the dyno guy what it would come out if done on a DynoJet .To compare .....he tells me he just adds 11.222 % to his dyno numbers and that what it would come out close to .The 11.222% is a guess....it is 11.#### % Im not for sure on exact #

 

Fluid...you need to get it tuned....to dang rich.....He has mine running 11.8 to 12.2 to 1 .Im going back soon to play with the timing .Im going to see if we can get rid of the dip at 5,700rpm and the big drop off at 6,500rpm

 

The ECU programming for the G35 (especially the auto sedan) flat out isn't the same as for the Z.

I was done on a dyno jet my stock base run was 208 HP on same unit only one in town. He tells me the highest he's seen a stock 5.0 is 187 HP so I 'm happy with my numbers. WE set the A/F between 11 and 12 from 4000rpm to 7000rpm I wanted to be very safe as the wife drives the car most of the time. BTW the owner of the shops Vega pulls 1004 HP and is street legal runs mid 8's in the 1/4!

 

Thats why Im seeing a big drop off of power at 6,500 rpm...they go from 4 to 8 degree's Does any one know if the Vortech [Split Second ] timing replaces the stock ECU timing or just adds to it ????

 

It doesn't replace the stock ECU timing... It simply retards it (i.e. counteracts it) by the number of degrees specified.

--Steve

 

If the the ECU is retarding [say] 2 degrees at 5,500 and the Split Second is retarding 4 degrees at 5,500 is then the timing retarded 6 degrees total ? Or does the Split Second over rides the ECU and its only 4 degrees ?

 

They are additive, but the SS programming is a negative number. A positive plus a negative equals a smaller number than you started with. The stock ECU actually *advances* timing at higher RPMs, so the Split Second counteracts that by pulling timing back by the specified amount.

THANKS....Zimbo...You have helped alot.
