Anyone else still waiting on theirs? Talk about slow

I can't imagine WHY they are slow... let me see... EVERY DSM owner should want one... just be patient bro... all in good time...

Yup, still waiting Just over two weeks now.

 

[DSMraver]

Be patient.

We've got about a hundred of them on the way, they do take time to be produced, ya know... This isn't something that is done by hand, it's being manufactured.

If you didn't catch on, I'm now working at Ramchargers, at their Livonia Michigan location. If any of you are local, stop in and say hi. You can laugh at my 1.8l NT daily driver, and soon you'll be able to gawk at my new 92 AWD. (/ego off)

For all of you guys complaining about waiting a few weeks.....

I waited almost 6.........


Now onto the good stuff.

Running blow through and a 3" MAS. RRE 660's, supra pump, AEM regulator set to 43 line off/ 38psi line on.

My base setting is also at position 8.

Running at the suggested setting the car misfires and blows tonnes of black.

I've only done a base setting right now, just got the pipes finished today..

I'll post more once I drive the car and get it set on a wideband....

Ryan, why are you running your F/P so hi, instead of the stock pressure of 38 vac line off around 27, with line on.

With so many running this way it has got me thinking about the settings. Assuming every knob position is 5% like on the other knobs and 450 is base then 5% = 22.5cc. First position is 475, second is 500 then 8 is 630. 8*22.5=180, then + base 450= 630. Just wondering, by the way I'm at 8 now because I couldn't take enough fuel off at wot on setting 6.

I highly reccoment keeping your sAFC controler when using the MAFT. If you use a pocketlogger you will begin to understand the limits of its fuel adjustments. I found myself having to lean out my stock injectors which operated at 106 duty cyclesafter base settings with the MAFT. I had no experience with dataloging when I had only an AFC. I was not getting the idea the MAFT made my logger seem less accurate. I might even think that simply having the adjustments on the MAFT, The fairly well integraded design allowed me to idle very consistency that made my Talon's Strength at idol a very strong. Much better idle with the MAFT isnstalled is what made understand that this HUGE Mas was a valuable upgrade. The only downside is that with stock injectors you will probably still hit fuel cut at say 18-19psi

to chime in.. 43psi base pressure is how all fuel injectors are flow-rated. The 1Gs have base of 38psi, 2Gs 43.6.
So using stock FPs.. a 660 would flow 583.26 on a 1G (-5psi) and 669.21 on a 2G (+.6psi)

On my 1990 I've got my trims perfect using 42 base and 550s using my S-AFC and 2G MAS (waiting on my MAFT).

Thanks, I didn't want to start an arguement.....
BTW, 11 psi drop with the vacuum line connected? I see approx 5psi drop. On a 1:1 regulator that means your car makes killer vacuum.

 

[Formz]

My car will make around 22in of hg on in gear decel, and about 19 in neutral (which is very good) and I only see a 5-7psi drop with the line on.

 

[DSM90AWD]

Sorry.. (-5) meaning 5psi less than 43psi for a 1G baseFP.
My vac on/off diff is also in the 5psi range with 19inchesHG at Idle.

Ok, I went to the dyno today and managed to get 301.9 whp and 291.6 torque out of the car with pump gas and at 18psi. The only problem that I had was that after 5500 rpm I was mad rich. I mean my a/f ratio was below 10. I did not have enough time to try and lean her out to see if my numbers would be better. I will go back this coming friday and see what I can do. I only used the translator to tune with, my safc was zero'd out.

I have a feeling that if I can get the a/f in the high 11 low 12s that I could gain a few more horses and some torque. We will see.

What was your dyno numbers before the MAFT was put on? What was the increase and was the only mod you made to the since the last pull the MAFT? Anyone else have any before and after dyno numbers?

Sorry, no before of after dyno runs. Car was not running right prior to maft instal so it was not worth it for me. The car, however, by the seat of my pants, feels like it has more power after the install.

Also the dyno numbers I gave earlier were corrected, the actual hp was 309 uncorrected. The new software release will hopefully make it easier for me to lean the car out.

 

[NOSLO2PT0]

Has anyone recieved a MAFT within the past couple weeks? I'm going on a month waiting on mine. I was told they were waiting on the 1G connectors and that they should have shipped last Monday/Tuesday.

Anyone?

 

[DSMraver]

They were backordered. They should be shipping soon.

 

[Vince]

I installed mine about three weeks ago and could not be happier
with the performance difference from the 1G MAS. My 550's idle
perfect with the base setting for these injectors, but I want bigger
ones.
Has anyone tried installing 720's or bigger with just the translator,
no AFC and got good idle? The manual states it will correct for 1250cc
injectors, but I want to hear from someone who has run pretty big
ones and has a good idle(no AFC).

 

[lxlaw]

Vince why dont you be the one to try it for us. Someone has to be the pioneer. I have a friend that is wondering the same thing. So if you test it he will buy the MAFT and probably go with even the next size bigger injectors.

 

[Motohead1]

I will say this. I would not install the MAFT till ya have at least620cc injectors or bigger. I am overrunning my RC 550s right now with a 14b ported and 3" exhaust. I have tried tunning with a lower base setting and tunning with a higher base setting and the end result is i need bigger injectors. I have found that for me the#3 base setting tunes a little better than #4 witch is for 550cc injectors. Buddy of mine is running 850cc injectors with a blow threw with no problems. It will be awhile till it sees higher boost levals as he is still breakin in the new motor. I see no problems running large injectors with this setup. I am gonna get some 750s soon. HTH

 

[snoopnoon]

I was wondering if any of you on this list would know if this would work?

i fell apon a LT1 MAF, off of a 96 Trans AM, i was wondering if this will work.

 

[lxlaw]

hey on like page 3 or 5 of this post there is a whole list of applications. Just look throught the first few pages and you will see which ones are interchangable.

You don't need bigger injectors, you need to learn how to tune, or buy other supporting mods. A 14b can barely outflow 450's, but you say you are overrunning your 550's? I hardly think so. 550's are just about maxxed out on a 20G, not a 14b. Do you have IPW/DC #'s to show that you are maxing out the 450's??? If not, what makes you think you are?

 

[snoopnoon]

I know for a fact that leon reitman with the greenmachine has run 11.3 on 550's, so unless you are running some fast times i also do not think you are outflowing them.
