DTAForum.com - a forum for the DTA ECU

I solved! I solved! :D First test, 1,5V AA battery on DTA input. ECU reads the correct value (about 1316mV on 821 picture. Second test, a flatline at 1 V for every AFR. In 823 picture multimeter says 1380 mV (ok) and ECU is disconnected. In 822 picture, ECU is connected and value becomes wrong (mult...

Ok, I will try using two flatlines, one at 0V and 9-16 AFR and the other at 5V and 9-16 AFR. However on Innovate output there is a change.... In 817 picture, at 10,8 AFR I have 1880 mV and in 819 picture at 18,3 AFR I have 6120 mV (full scale is at 16 AFR). It seems to work.... When I connect the ou...

You got me a good advice about narrowing AFR range (9-16), I did it but I still have my trouble.... In 809 picture, I built an Excel table of a linear sensor (0-5000 mV and 9-16 AFR). I set Innovate to same values and I put Excel values on DTA. At 12,5 AFR I should have an output of about 2500 mV. W...

The other three images...

Hello everybody, thank you for your answers! I had some other tests... First trouble was that from Innovate I had a wrong information about connections. When I bought my LM-2, I didn't know I could need an analog cable and now to have it I should pay expansive shipping cost related to its price (and...

Hello again... Here a new question.... I've a S80 PRO and I have a trouble with the lambda setting. In the past I had a test and all seemed to be ok. Now I started to work on ecu setting...... I connected my Innovate Motorsport LM2 output to the ecu and I changed the setting on DTASwin. The strange ...

Ok, I think I understood.... I can use 8 same size injectors and when setted twin injectors, in main fuel map there will be a bigger opening time (more ms respect single injectors). By blend map I will change % of main and remote injectors. 50% will be half time inj1 and half time inj2. But with twi...

I would use 8 injectors of same size. 4 of them always active, the other only in some conditions (RPM/load) together main. Is it possible?

Ok, but if injectors are of same size, how is possible fuel flow change? 0% all fuel from inner, 50% half from inner and half from outer (no difference) and 100% only from outer (no change, they give the same fuel of inner)... This is the reason because I thought it needed bigger outers...I'm confused

Hello, I'm interested in understanding twin injector function of my S80. I would know if in my 4 cylinder engine I have to buy 4 bigger injectors to have a commutation by the blend map. Or, as I preferred, if I can install 4 more injectors of the same size that will work together. In this case, how ...
