Mapclamp tuning... - SRT Forums

TrevSRT · 12-09-2005, 12:54 PM

I just installed my mapclamp on my car at the pre-setted settings from dasmopar....

when I do a 3rd gear pull soon as I go wot it hits 11.0 and rises to about 11.8 a/fr near redline...

4th gear hits 10.8 at the bottom of it, and towards redline it constantly rises, and at the end of 4th I have: 11.9 a/fr

should I leave it like this (this is how it came with my mods below is my a/fr, the mapclamp is unadjusted from being received)

I am using the agp wga to spike 18, and fall to 15 at redline....any help is appreciated, thanks!

Does it feel stronger?

You know actually I'm really curious as to your opinion on your current setup. I'm trying to decide if I should get stage 2 or go with stage 1 and mapclamp. Do you notice big increase in power over stock with all your mods? I was going to go stage 2, 3" turboback and that's pretty much it. Think your setup is faster?

Preset? As far as I know, Das does not sell them pre-set for obvious reasons.

Having it hit high 11s or right on 12 on the intial punch would be good but your higher rpm afrs won't allow it by much. Leave it like it is.

Only tune the map in 3rd. It runs leaner than 4th. If you tune in 4th for a good AFR then 3rd will be too lean.

Yes, they are pre-set from when buying them, just tuned way down from my understanding....

Anyway, before the mapclamp I tested my afr's........(3rd gear pulls)

10.9 as soon as I lay into it, at redline it hit 11.2 max....

after the mapclamp which I just received about 2 hours ago ad just got done letting my friend soder it for me, we did the following runs that I posted in my first post. ( so obviously it is preset, or mine was).

And the first post was a mess-up, I am spiking 17.5 - 18psi and falling to 15 at redline.

So you suggest leaving it like it is untill I get a fuel return line, or ptperformance's fpr mod...?

Is 12.5 afr too lean? I heard some people are letting it go this high, is that safe?

Yes, it is a HUGE difference over stock with all my mods.....the car with just adding the mapclamp (which just got installed) pulls alot harder all through the powerpand.

And I don't get that feeling in 4th gear anymore that i use to before the mapclamp, it felt like it pulled alot of timing in 4th (car was really slow when switching to 4th gear, now that I have the mapclamp i don't feel that anymore.

sorry i didnt read everything but what is your MAX boost? never mind i see its 18 psi falling to 15 you may up it just a little if you had a return line you could go to 22/23

if its 18-20

start turning the clamp to the left try 5 turns

recheck

now if its still the same

do one turn incraments until your at 10 turns 5+1+1

so 5 truns check, 1 turn check repeat till 10 turns or until you hit target a/f

if target a/f has not been reached but some changes have taken place do half or 1/4 turns

due to the nature of the stock turbo srt peak boost is hit then it falls off you will be adjusting the LOW a/f ratio not near redline do all of this in 3rd shoot for 12.0 then check in 4th

i like to get it 12.2 in 3rd hope this helps

Go with what vector suggests. 12.2 in 3rd. It's a good safe afr.

Vector, since he is running leaner at redline then at the initial punch wouldn't he want to lean the high rpm AFR to 12.2?

MikeCandler · 12-09-2005, 02:19 PM

Vector is the man listen to his advise

IWantAn04 · 12-09-2005, 02:20 PM

hey vector if i tuned for 12.0's in 70 degree weather....how much leaner would it be at 30 degree weather. Too lean i know...im just wondered how much will it change

Sorry to hi jack, but would it work to map clamp a car that is on pcm controlled boost? So the power will be increased but driveability will be maintained?

in order to effect the higher RPMS where he is alread in the upper 11s he will need a return line or something

and really in order to effect it your going to have some serious clamp on the car

its better to be on the green or blue (i like greed line setups the most)

really it isnt the best to clamp it when the PCM controls it. because the PCM is flying blind then and it will effect the pcm's EBC and you may have erratic boost
