Injector pulse width ????

Can someone with GTA Adaptronic please look at their injector duration values from cold and let me know .

Do you mean the enrichment percentages or the main fuel map? The enrichment percentages should be the same regardless of injector size.

I'm enriching by roughly 40% @ 10 deg C down to 20% at 45 degrees. Zero from 80 deg onwards.

As for the main map, I've got a good map for 440cc injectors so your figures should be near enough double. 1.7ms in the idle area on mine which is deliberately a little rich

Cranking fuel is 60ms @10 deg decaying linearly to 35ms across the board from 35 deg onwards. You'd want to double these figures. Short and long post cranks are 40% for 3 seconds and 10% for 10 seconds respectively.

I realise this isn't strictly what you asked but it should get you going assuming you're on the trigger wheel ;) Rob's now done over 2000 miles on his new engine, driving it every day. His was "the DeLorean with the dump valve" at Silverstone (as someone came over and asked!)

No , I'm on the std fly with the tweaked PG map .I need to know the pulse width not the enrichment values .I've got mega over fueling ..........the 25t ecus won't run the car well at all .The Adapt does on the PG map but it's 2000rpm from start and runs all over the place ..........doing a similar thing to our previous outing when we struggled to get it going , rich and no power .
Checked all sensors ,idle valve ,throttle pot ..................all good .Rewired injector loom and idle valve as it had loads of bare wires .

The renix won't run it at all...?! That's wierd and suggests wiring probs?

Check all sensors are calibrated and do a "sanity check" in live gauges (F2) that they read sensibly.I've always though that the fuel map on a stock flywheel will be fine as the ECU resets correctly on each period, but the ignition timings are likely to be out. You have Rob's map anyway so you've got a good set of figuers to be getting on with - note how different the ignition map is from that peterg6 map! In particular look at how the ignition values haven't been tuned for revving under no load - no advance whatsoever. If yours will run with the peterg map, you could start by re-writing much of the ignition map

Rob's map is calibrated for a GM 2 bar standard MAP sensor

I also ran Rob's map on the twin turbo DeLorean, altering the fuel map for his 337cc injctors, and the MAP sensor for his cossie one... it started and ran just fine and was perfetly drivable.

One thing I will suggest: flash the ECU with the latest firmware and run the latest Wari. It's quite easy for the ECU firmware to get corrupted.

Renix unit # 2 runs the car now .I have rewired and checked all the top end loom .It is over fueling and will idle but at very low revs ,but that may be the bigger injectors .Got the renix manual out checked all resistances ,replaced the water temp sensor as that was way out ,reading for 80 c stone cold :roll:
Traced all wiring back to multiplug and checked against loom fitted on the 25t lump in the garden ,all good .
I'm just about to flash Adaptronic ......................
