Would it be better to install my 1220s and log maps on MAF for base Speed Density tables OR map what I have then change to speed density AND the 1220s simultaneously?

Just recently converted to speed density, I have the car dialed in pretty good cruising and what not but at WOT it seems to get knock 2/4 pullsFIC 1250cc injectors 255 walbro -6 lines everywhere fuel lab filter aeromotive fpr set to 40 psi fp red turbo greddy bov 2.5 inch piping mishimoto...

So it seems 99.9% of people just run the GM IAT for their SD setups however I have been spending hours trying to locate one and it's proving impossible. Being in Europe, it seems this sensor is not sold new by any retailer or parts store. And I have also checked most of the GM vehicles for parts...

Can anyone tell me where my MAF sensor is in this picture, I've been looking for it for 2 hours and I can't find it. At this point I'm thinking that i done have one on this car, I found the original build thread on this car and it says that's it has dsmlink v3 full on speed density but I can't...

Is there a way to get the big maps speed density ROM and XML files for a black box ECU? Or anyone willing to share.. Ceddys site has been down for a lonnnnnng time and I sent him an email but never got a response.. Any help is appreciated.

Hello,I recently purchased a heavily modified 1G with ECMLink V3 running Speed Density. However, it is running very rich and will barely start or stay running due to the plugs fouling almost instantly. I've pretty much narrowed the issue down to Speed Density not being setup correctly by the...

I recently switched to SD. After getting a base tune loaded and a short cruise and a WOT in 2nd gear at the end. The AFR goes pig rich. I've done a compression, cylinder leakdown test and boost leak test. After banging my head against a wall i am at a loss. Ive attached a log

Just bought a 1998 GSX manual that has an ECM link V3 HX35 1200cc injectors FPR not sure about the fuel pump but it was upgraded i think since it made 400 wheel on the dyno. The story so far is the car has been sitting in a garage for 5 years and i bought it from this girl who owned it that...

So I have just purchased a car with speed density. It looks like the previous owner did some things that were not correct. I am trying to fix the pcv system. Initially there was no pcv valve and that hose was run back pre turbo. The valve cover vent was run to a catch can with wire stuffed in...

So I’m trying to start my dsm with the eprom dsmlink ecu and all i get is cranking and cranking no start. I’m also on speed density with a gm iat and 3-bar. Have gone through several settings in dsm link and also got my battery changed and alternator bench tested. I put my non-eprom 97 ecu back...

I had a bit of a one off question.Why do speed density setups use intake air temperature instead of manifold air temperature?Is it because it's just easier to install and use a IAT sensor than it is to place it in the manifold, or perhaps some engineering issue with early MAT setups that...

I'm going to show you how to hard-wire your SD kit and Flex Fuel sensors instead of using an adapter harness for those either redoing their engine harness or you simply don't have the funds for the adapter harness.There was very little information on MAF wiring that I could find but maybe I...

Hey there DSMers, I've run into an intermittent no start condition which I believe I have pin-pointed down to the MAP sensor. It's a mitsu style Omni 4 bar, about 3-4 years old by now. I have checked timing, spark, and fuel. Didn't get the chance to check compression before I killed the battery...

Hey guys! Have a conundrum I cant seem to figure out. I just installed speed density plug and play bundle from ecmtuning and the car starts, idles really high (2500+rpm) for 10-15 seconds then slowly dies out... Giving throttle immediately kills it. Plugged the 2g maf back in and it runs and...

Car was running great when I first bought it but due to a recent battery drain issue all of the previous owners ecmlink settings reset and now it just cranks and backfires if there's anyone around westchester who be willing to help me get my car running again I'd really appreciate and i would be...

Hey guys ive had my car for about a year now when I bought it it was running great on the previous owners tune. Unfortunately the tune reset possibly from low battery voltage? And now im very lost on getting it back to the way it was. Ive been constantly dealing with idle surging, incorrect AFRs...

I just bought my first DSM, a 1997 Eagle Talon TSi AWD and am looking for a general sense of what I should tackle first in starting to throw money towards it. The previous owner has already started modifying it so I wanted some knowledge on what parts I should upgrade in addition to some...

I've been looking for the answer for hours but haven't been able to find anything on this. So I am running speed density and have already payed someone to tune the "turtle" with my BOV recirc'd to the IM. My question is, if I just vent the BOV to atmosphere now, will it mess with my tune? I...

I have my AEM digital wideband all wired up and working properly (as far as I can tell). The sensor is installed on my test pipe in front of the rear o2 sensor. I am trying to tune for speed density right now before I throw in ID 1050X's, Fuel lab FPR, AEM fuel rail, comp 102s and kiggly SS...
