I have a 93 octane Nelson tune with TM removed and plan on spraying a TNT 100hp wet shot on my 03 ECSB 4.8! Any of you running N20 with Nelson tune or Edit have to retard your timing? I havent talked to Allen as to what my timing should be at but I will. The thought im having is I dont want to get a new tune from him with my timing retarded adn lose performance when Im not spraying which is gonna be most of the time so I was thinking about getting one of those Timing Tuners from Imperformance! Any of you spraying or that can help me out Id appreciate it!

 

I would do it that way, get the tuner to automatically retard the timing, if not you will lose a little power with a n20 tune. You won't lose a whole lot with a n20 tune but the first way would be a little better.

 

I dont know if Nelson can do this, but the guy near me can tune using the MAF with a dry kit that will automatically retard timing when the N20 hits the MAF. Iver personally ridden in a C5 that made 43X rwhp with heads cam and then made 53X with a 100 dry shot. Well, it ran strong.

 

I think he said wet kit.

With a dry kit, you can tune the timing lower when the maf sees the nitrous using the upper flow numbers in the timing table that you don't see NA.

With a wet kit I don't know how you'd do it since the maf doesn't see a wet shot.

 

i do know that allen has been using a 100 shot with all his timing. i am going to do this soon and i am going to try it without the tuner first.

 

So you are saying since it is a wet kit that the timing tuner wouldnt work? Anyone know for sure? I havent heard back from Allen yet about if I even need to worry about the timing but I saw this think and thought it was the fix for my problem!

 

no i didnt say that. the timing tuner does work with these engines.it works good. hooks inline with the crank sensor. i am going to try a 75 and a 100 shot without the timing tuner.if i get knock then i will get one. if not i wont for now.

 

What he is saying is that the tuner will work with a wet kit. Using the maf to adjust timing will only work on a dry kit. 02 is also saying that Allen is using a 100 shot with his 93 Tune. So if he is doing it then you can trust it to be ok.
