I have installed DLI2 with NGK BPR9ES with 0.023 gap. Ecuflashed.
After 2 days running, parked the car and started it after 6 hours.
It worked fine only 5 sec, then missfires occured.
5 min took for parking. Saw that right coil burnt and flowed.
I took out DLI2, changed spark plugs for stock, BPR8ES, coils, burnt new coil again (right one) second time. Gasoline on sparkplugs from 1st and 4th cyl.
I have not change stock long wire between coil and spark.

Any advice would be appreciated

 

hmmm..had this problem a few years back when I had a greddy E-manage installed...burned a few coils well

after about 4 pairs of coils I found out that the Emanage could've been causing it....

took it out and that's it..no more burnt coils.

I was thinking it would've been the DLI but if you said you took it out then I'm not sure

 

check over the wires on the ignition amplifier it should not be burning coils what are you using to tune the car with

 

your DLI did it. And maybe fried in the process of doing so.

it happens.


also i'm 550whp with no DLI i use to run one. why do you need one at 390?

 

ecuedit, but dli already took off and problem is still remaining. 2nd coil was burned without DLI2.
Could the burned coil destroy spark or other way round?

 

so your coil burned without the dli on? cause smokedmustangs DLI burnt a coil on his car.

 

First burnt with DLI, second - without (on idle in garage)

 

You gapped your plugs at .23? A little close isn't it?

 

Yes, the gap was 0.024'

 

Guys, what do you think about different resistance values on left and right coil connectors? Left = 1.395 kOhm; right = 0.665-0.679 kOhm. What should I repaire in ECU?

any variants?

 

i run my plugs lower than .023.

Your DLI very well could have fried both coil packs. Or you got a bad one.

When smokedmustang's DLI fried his coil packs the DLI also went bad. We tried it on my car and it made my car miss. Removing just the DLI fixed it. I wouldn't use the DLI thats for sure.

 

Cyl #1 and #4 run off of the same coil pack ( waste spark ignition).
If the transistor receives voltage from ecu for too long it burns up. Unless you have two bad coils in a row, I believe you need an ecu.

 

I`ve allready changed both coils, but

 

does anybody have ECU 8 circuitry?
