DASC Preperation

[DJ_AutoX]

Ok so im sure that this might have been posted before, but i did search this material and couldnt find exactly what i needed. I've got 2,900 in the back for the DASC, but im starting to get second thoughts. Im worried about what kind of engine preperation i need to do before i decide to throw the DASC in there. Do i need to switch from AMF to MAF (i have a 95)? Do i need to worry about thermostats, fuel gauges? What do i do about ECU, by the time its in there i will have a Dinan engine chip (i think, unless someone can suggest better), so am i going to need the chip re-flashed? If so, where can i send it that would do a good job?

Sorry if this is a repost, but i couldnt find anything like this. Thank you much guys!

talk to dusten.

you shouldn't have to have the chip reflashed. Replace any plastic coolant hose connectors that go to the engine if you can, they went bad on my car

Here goes:

No engine prep is necessary. I recommend installing a boost gauge (important) and a fuel pressure gauge (less important) along with the DASC. Yes, replace as many plastic coolant pipes/connectors as you can while you have the intake manifolds out. Also, if you are thowing a code of anything else, take care of that right away. Don't touch the ECU!! That Dinan chip will NOT work with the DASC! The chip advances timing too much for forced induction. Save your money for NickG's software (www.techniquetuning.com). You car will run fine without software, but I guess it make a nice difference once you have it. You don't need to switch from AFM to MAF, and you don't need to worry about thermostat. The DASC is the best put together kit I've ever seen, it included EVERY part needed, every gasket, zip tie, hose clamps, etc... All you need to tools.

Do it!

well said dusten.

Wow dusten..amazing. that gave me everything i needed to know! Thank you much. Ill be sure to stay away from that Dinan chip now. Two questions if you dont mind, What should i replace the plastic tubing with, Rubber Tubing? and where can i find a boost guage for the DASC? Thanks again.

Replace the collant connectors with the OEM replacement parts. There are two of them. I'm in an airport right now, so I can't look up the part numbers for you, but cali-ti or Tyler has them (I think).

Autometer makes good gauges, you'll only run <10psi, so try to find a 20psi boost gauge. You can order online from ebay, egauges.com, or go to Autozone, they have them in stock.

I couldn't agree more.

I second the fuel pressure guage, I fix way too many broken race cars because they didn't know the pump was dying and went lean.....Make sure the guage taps in as the last thing before the injectors, it will help spot plugged filters and such that way, as well as a clogged return line(Too much pressure

NickG doesnt make any type of ECU to work with teh DASC for the m42. If i cant use Dinan, and no NickG..what am i looking at? I want to eventually increase boost, replacing the pully and the injectors, but what ECU am i going to run. I know that there is no way a stock ecu can handle the DASC. What about a type of piggy back system that uses the stock ECU and just flashes the map, sort of the like the Cobb Access port for the Subaru's..?

[cali-ti]

they made the DASC to work WITH the stock ECU. it's only if you want further stages of boost that you need to worry. once i get back from some shopping, i'll find those part numbers for the plastic coolant parts too.

EDIT: the two evil parts ...
01 CONNECTOR 11531714738 $14.17


well ... it appears the 95 does NOT have the second evil part, you luck out!
09 CONNECTOR 11531743679 $7.81

Thank you for those pics. So my only question is, if i want to do higher performance after the DASC involving ecu...do i need one specially made from NickG or something?

You can run a piggyback fuel/ignition controller. Check out the split second stuff, I guess they work good with BMWs. PM Chad (ZeroG), he's running a Split Second controller on his DASC'd m42.

Thanks so much Dusten. you have answered every question i have wondered about. You are def. a god in the 318 world

hello all,

I ran into some trouble while trying to instal my DASC last night.. broke of the $14.17 'CONNECTOR' by accident... but was wondering what is the significance of replacing the $7.81 connector (even though I'll get it anyway just to be on the safe side)? will it fail due to increased boost or should I excpect to 'accidentally' brak eit off as I did with the other one??
