ECMlink Noob to DSMlink but not DSMs.

Looking good but your idc is hitting 90% @ 6k rpm and 35 lb/min...you're going to need bigger injectors if you want to take it further. Get that wideband in asap! and zero out those fuel sliders

 

[SpdMongrel]

I moved the fuel sliders to keep the idc under 100%. Im still looking for injectors.

Well guess I can hang up this tune. Replacing the engine.

What happened?

Ouch.. No Good. What happened???????

Driving down the interstate to pick up my daughter over the weekend it started running warm. Coolant temp was running around 226. So when I checked my coolant it was full but had what looked like soot floating in it. I got it back home did a compression check and it was within service limits. I decided to do a leakdown test and had 60% leak on 3cylinders and 80% on 1

Well just to update.... Ive got my built motor installed and back at tuning again. Im waiting to post any logs until I can get my WB logged and take care of a nasty boost leak caused by my BOV.

Does anyone have global and deadtime for lucas 120lb injectors. I think I have it but just want to confirm.

The lucas are similar to dephi and are 1200-1260cc by conversion. For comparison Ecmtuning has base data for delphi 1000 at global (-51) and deadtime (450).
There is a "calculate" function in the Fuel tab to get a close global number to input.
This is not exact but i would start with global -57 and deadtime 490 and go from there. You can use Stft and Ltft Lo to get close to zero % at idle to fine tune.

Dsmlink was wanting me to use 62 and 360 on them. Didnt work so well

Try the numbers i posted above and go from there. Usually the starting point never stays the same. You will have to fine tune by adding and subtracting on global and deadtime until you reach a stability.
Stft fluctuates with deadtime increments
Ltft Lo fluctuates with Global increments
Start with the initial numbers and adjust from there to get stft and ltft lo as close to zero as possible.

Ok, thanks. I'll be back at it tomorrow.

Im still looking into running my AEM wideband into the link.

Be sure to set it up as a linear wideband then and adjust the voltages accordingly, not just as a AEM wideband.

 

[SpdMongrel]

Yeah, found that out the hard way. Think I've got logging accurately now.

 

[SpdMongrel]

Well been awhile since my last update so thought I would post up the latest. Got rid of the Maf setup and now running SD. My ecu has a issue with the IAT circuit so cant use that function yet but have got it setup pretty good now. Heres my current log.

That actually looks pretty good, especially for not using any IAT correction for the VE table. You need to richen things up a tad above 6500rpm in the higher load cells, but other than that it looks pretty solid.
