first time with dsmlink and my car wont run it just spits and sputters

[97-gst]

Installed dsmlink v3 lite, changed coil on plug primary ignition wires, inverted cas and the car does nothing but spit and sputter then dies. unplugged the ecu and switched
wires back to normal and it runs fine off of the maftranslator. Whats going on?

 

[black_gst]

if you swap ign wires i dont think you need to invert CAS

 

[97-gst]

i tried it with and without and it was still missin.

i tried more fuel less fuel i even had it set for 450 injectors and it was still sputtering.

I just installed walbro 255, 1050cc injectors and a afpr

 

[black_gst]

post a log or the car trying to idle... and have you set up your account on ecmlink.com yet?

and what do you mean by

"unplugged the ecu and switched wires back to normal and it runs fine off of the maftranslator."

are you saying it runs good with the maf translatior but not with the stock maf? clarify please.

 

[Guzman08]

just one thig is the ecu damaged?? and u can email thomas d about it and he will reply pretty fast.

 

[97-gst]

it has a 3 inch gm maf, atmosphere bov and when i put the stock 97 ecu in and tune with maftranslator it runs fine. but it doesnt do good at all with dsmlink.

I dont think the ecu is damaged, it can cut the fuel pump on and off, it just seems like the car doesnt want to run. shouldnt 1050cc injectors be set at 57 percent?

You need to take a step back, slow down, and post up a log.

I don't think any of us can make heads or tails out of what you are saying about the connection between the stock ECU and MAF translator.

 

[97-gst]

i'll make a log in a few, but i dont see how its gonna help anything. i have to crank and crank and then give it gas while im cranking and itll fire and then i give it gas and nothing give it gas it revs a little. fighting to keep it alive itll run for about 5-25 seconds.

i mean i set the maftranslator for 1050cc injectors. then i installed eprom ecu and swithed primary ignition wires and no matter what i do it has a bad idle. So, i put the stock ecu back in and switch the wires back they were originally and unhhoked my laptop and with the maftranslator set at 1050cc injectors it runs fine.

It will allow people to look at all your initial settings and see if you are missing something in the configuration.

 

[black_gst]

with the maf installed didnt you have to cut the maf wire on the stock maf plug? did you reconnect this wire?

For a 1997 car with a 1995 eprom ecu, you still have to change the fuel injector wires at the ecu plug. If the spark plugs fire different, remember that the fuel injectors fire at the same time as the plug wires just earlier in the cycle.

 

[Guzman08]

do you have the stock maf sensor.. try that out with the dsmlink

 

[GSXSixteenG]

Make sure you have the correct injectors, deadtime, and global chosen. Also, make sure you have the correct MAF selected under misc. As stated above, if you had a log we would see that.

did you do that or not???

Matt, I didn't see anywhere that he said he was running a 1g cas. If he's still running the 97+ style cas, all he has to do is invert the cas check box and switch the order.

 

[97-gst]

i dont have the stock maf. I have a 97 cas, so do i still need to swap fuel injector wires? does the box you have to check use non 95-96 cas because thats the box i checked

 

[GSXSixteenG]

Yes, when you check the box you still have to switch the plug wires. Do you have the GM maf chosen as your maf on link? I believe its an option, don't have my tuning laptop in front of me.

[97-gst]

no it wasnt an option. it said if i am using an aftermarket maf to select stock maf because thats what gm maf simulates

yes....went to start my car up today and its running great. i guess it was just flooded bad. now ive gotta figure out how to lean it out some its running 18.0's and off the wideband

 

[GSXSixteenG]

18.0 is lean not rich. 14.7 is stoich, anything below is rich, above lean.

 

[nsrmotorsports]

Update on this?

 

[97-gst]

okay then its running real lean. whats the best way to make it 11.0? How bad is it to drive it on 18.0?
I tried to post up a log but im not real sure how to

[97-gst]

okay i got it, datalog1 is the one i did last

When you installed and ran the car using ECMlink, did you change the injector settings in the MAFT box back to stock 450 settings (AUX - 4, BASE - 2, Everything else - Off)? From this post it doesn't sound like it.

i mean i set the maftranslator for 1050cc injectors. then i installed eprom ecu and swithed primary ignition wires and no matter what i do it has a bad idle. So, i put the stock ecu back in and switch the wires back they were originally and unhhoked my laptop and with the maftranslator set at 1050cc injectors it runs fine.

If not, you're basically adjusting for the injector size in two places - MAFT and ECMlink.

 

[97-gst]

yeah i was reading and i came across a page that said set for 450 injectors. I did set it to 450 maybe thats what finally got my car to start. So to get my afr to 11 to 1 do i need to cut down my injector size?
