Some of you guys may know the glitches Ive been having with Ramchargers Timing Tuner. It worked just fine for a while but will sometimes throw the timing WAY out of whack. Fortunately its always been towards retard and not advance. It always seems to act up at the worst possible moment too. 1 mile from bradneton during the last TR track day, just priot to racing 01Bird of Prey this weekend, and a few others too.

Well I got with Jeremy at Fasterproms.com and we discussed potential ways to get the level of retard I need to run a 300 shot without the Timing Tuner. After a few failed attempts we came up with a sound theory. And he immediately went to work on the solution. It was in depth...and involved multiple tables...but let me tell you...it works like a charm.

I can now take that Timing Tuner and toss it. All I have to do now is arm the nitrous and spray away. Computer does the rest without a worry. And when not spraying my all motor program is still intact and operative to max power. Which was the difficult part. How to give the best tune for 700 rwhp one second and then for 430 hp the next without touching anything except the nitrous switches. BIG PROPS TO JEREMY on this one. AKAIK no one else in the country has made this leap yet.

So some of you guys that run larger nitrous shots and are aprroaching the area needed for some timing retard can get with Jeremy for the custom nitrous tuning.

 

Very Stealthy!

 

Actually Al that is great. Your comment that no one else has made this leap yet is not true.. Harlan was the first to discover you could do this with ls1edit and tuned his table at every boost level above 8psi to 20psi.. That is how he gets around using a stand a lone computer. MTI has been doing it for awhile now as well.. All of their nitrous vettes running 9's have the same setup you are talking about. Futral Motorsports did this with one of his Supercharged customers. Most tuners do not like to do it because it is a pita and requires much thought.. Congrats on the new tuning. I guess I can test out more timing now on the dyno...

 

I dont think this is the same thing Vince. . MTI uses wet nitrous with thier cars. Im not exactly sure what they are doing...but if its a wet kit...its not the same thing I believe MTI was just changing the tune on the car before running the nitrous. And the Forced Induction is not the same thing since they are not worried about going WOT on motor alone with no boost. The big difference here is that its max performance on motor and will also take care of the nitrous when needed..with no changes in between. At no time does Harlan or other FI guys go to WOT without boost. I go WOT all motor, then I can go WOT with a 300 shot. And tuning is there for both circumstances.

I think others could figure it out with a little time. But no one really sprays large dry shots on LS1s. 99 Redhawk (brooke) was the last one to do large dry shots...and that was before LS1edit.

 

You are correct that you cant go WOT on a forced induction car w/out going boost, but I think you kind of missed what I was saying. On a boost setup you could either leave the tune setup for low timing all the time or have NA timing until boost kicks in and the timing is automatically reduced. The reason they do this is to keep also gas mileage while not in boost.. MTI does use wet kits, but I spoke with Jason from MTI a while ago and they do not change the program before spraying. Even with a wet kit you need to adjust the timing on a big shot. If not then you made me buy the timing tuner for nothing..

 

Any large shot will require retard..wet or dry. Im not shure what MTI is doing but if its a wet kit its a different method.

Either way big props to Jeremy for allowing me to run without add on boxes.

 

How is retarding timing on a wet kit different than dry?

 

Carl, my guess would be that Jeremy is basing it on MAF readings, and programming the tables to see that and adjust???
Wet would require a different "trigger"...
Al?

 

Well it sounds cool. So congrats. Oh btw, you should take it to Sams to dyno it this Friday night. That would look cool too.

 

That is why I used forced induction as an example as well.. At over 500rwhp you will have to modify the tables to get it to work correctly. Even though a wet kit adds its on fuel, the pcm still needs something other than detonation/kr to tell it to retard timing.. What Jeremy has learned to do has already been done a year ago..
