Re: Z31 - Wild switch at 141*F(60*C)

I'm pulling the car out of storage today so I will tinker with it from a very... very cold start. :lol: I just updated Nistune as well to 1.2.57 and I see the check box and also the adjustment for the batch/sequential temp switch. So ready for summer after a solid 6 month long winter! Thank you

Re: Z31 - Wild switch at 141*F(60*C)

Sorry I've got about 20 support cases to work through at the moment. This one required some intimate bench time with a Z31 ECU and your tune Okay so 60 degC is the switchover point between batch injection and sequential injection 1.95ms both injectors are firing same time, after 60 degC it switches...

Any luck with this issue Matt?

Here it is Matt. The log I posted was not taken while running this tune but this tune had the same issue at 141F.

Z31 - Wild switch at 141*F(60*C)

I'll upload the log. It's short and sweet and illustrates what I'm experiencing when the ecu reaches 141 degrees F (60 degrees C). Injection time shoots up and goes very rich. I don't understand what could cause such a drastic change. 87 turbo Automatic computer (trans has been swapped to a manual) ...

Re: Cold start leans out till death

I made some serious adjustments to the Cold & Warm Enrichment and I think I'm on the right track now. I noticed today that when my temp got to 140 the car's idle smoothed out as if it switched to a different map. I haven't read anything about this situation anywhere. Maybe Matt can shed some lig...

Re: Cold start leans out till death

I don't see a table labeled "Temp Enrich" exactly. Just "Enrich (Cold Crank)" and "Enrich (Warm Crank)"

Cold start leans out till death

This is only during cold starts. I crank it over and it pops off beautifully, runs great for about 5 seconds and then the A/F just dives lean. I haven't been able to pinpoint at what temp this issue subsides. I have adjusted cold/warm cranking enrichment tables and they are identical to each other. ...
