Default Update on my MS

Ok, so me and Tom (brgracer) spent over an hour on my MS with the result of... it still doesent work. First, he went over all my settings, then we plugged it in. it would turn over for a sec, then hydrolock. So we messed with cranking and afterstart settings, and couldent get it to work. it would eaither not catch at all, or hydrolock. We got it to run once but it ran REAL rich, like my problem before. We then proceeded to try his MS, his stock ecu with his wireing, and nothing worked. We ruled out the MS hardware wise, my boomslang, and my ecu. It stumped the both of us....

I am going crazy

My MS is powning me :fm:

P.S - we had my cranking settings at 2ms al the way to 25 ms.. it made no difference.

1) I loaded DIY autotune's base map into his MS and then changed req fuel for his 330 injectors as some of his base settings were wrong, but no dice.

2) I then loaded DIY autotune's base map into MY working MS and again adjusted req fuel and plugged it into his car and it did the same no dice.

3) Thinking it was his harness, I swapped in my complete ecu/wiring/MS w/ DIY's base map with adjusted req fuel and still didn't work. FWIW, my MS setup runs fine.

We did adjusted cranking pulsewidths as well as afterstart enrichments in both directions with no change. Weird thing was that the injector pulsewidths would adjust ABOVE 9-10ms if we increased the setting, but they would not go below that even if proper cranking cells were set to 2 and ASE lowered.

He built the MS and harness himself, but still didn't work with MY MS and harness. And my MS was built by the best.

Ok do you have a stim? If you hook it up, does anything or everything work? Did you do the test throughout the build and pass them all?

Ok, put a timing light and see if your getting spark on all 4 plugs. Try reversing the wires on the coilpacks. Pull the plugs and see if they are sparking at all and if they are hot and consistant. See if the plugs are fouled or have raw gasoline on them. Determine if your having a fuel or spark problem.

firs off, the car runs perfect without the ms. its running right now as a matter of fact.

With the MS it wont idle, so I cannot read the timeing

as for checking spark with the MS, I should prolly do that.

Check your warm up, it might be so rich with the 330's that its not letting the cold engine run. When I swapped in my 460s from my stockers, I had to lower warmup considerably.

both are, just the jumper for one is one the back and the other is on the front.

They are 305cc injectors, high imped. from a supra.

We tried to start the car when it was still warm, and we changed the warmup alot..

next time you put your MS on tom's harness, you need to swap plug wires 2&3 with 1&4.
