in my experience thats a good sign that the cranking fuel is not enough, stopping then starting again stops the fuel pw from decaying or switching to the second stage cranking table, which has lower numbers than the first stage!

Hmm, that said, unusually I left off a vac line the other day.. only the brake booster , it cold started without hesitation and then went to about 1500rpm instantly... then stalled once the ecu tried to reign it in.

I was tempted to try the small vac line to see what the result was... I was thinking overfuelling.

Thanks for the feedback.

Hurrah, my new injectors arrived... but the missus needs the car for the rest of the day... boo!

Somehow oblivious to the fact the listing said 8 injectors... I have two spare now.
Worked out $AU140 .. bloody cheap ... oh, and another 40 odd for the ev6 adapters.

The next mission is ready to play with. Probably shouldn't get so excited, but hey. This engine has grown on me.

Cheers!

Interested. Where did you get all the injectors & ev6 adapters from ? Are they sized to suit L67 or N/A ecotec ?

Cheers

about 40lb at 3.5 bar

The1 had a thread about injectors a while back, some rouge sold them modified as larger injectors to a customer but they were not 100%.

However, it seems in stock form they are about right for the L67...

The1 wrote: ralcool, yeh ive had those in my VS V6 N/A doing testing for quite some time, they are a nice injector and id say for the money there a very very good alternative to the very expensive EV14 Bosch injectors, like what ID uses's, if 39LB is enough then id recommend them, i have put them in a few L67's now and run well, the only downside is you need to fit EV6 to EV1 adapters but there cheap. Ive had no problems getting a set to flow match under 1% using 2 sets.

Bold type added.

I looked on Aliexpress and there were a couple suppliers, picked one at random and waited 2weeks.

I got the adapters from DirtDevil on evilbay. $7ea

Very interested to see how they work out.

......

In other news, I went looking to see what my Bluetooth OBD adapter looked like on the inside... is it wired to aldl/J1850 or just obd2/ISO9141.
If I'm not mistaken thats the protocol type vs pins.

Its wired to all three, CAN J2284 too apparently... I'm now wondering why ALDLdroid didn't see the ECU.. might try debug mode too see if any comms are happening, might be something fixable.
It was only a cheap $10 adapter, but so far it has paid for it self on a VZ V6 with Torque... so its not complete crap. And common.

......
Also confirmed my other 'not working' usb-obd cable is a simple ch340 to obd2 only... not so useful for me.. could modify it, but no need.. FTDI chip instead!
Just to to wait for it to arrive.

Cheers!

Hmm, Something like this could be even better.

Diode and resister trick to Rx/Tx .. surely couldn't be that easy....

Edit, I've learned myself into an error, aldl 8192 comes out of pin 9, Regardless- I know how to hook up the FT232, its even easier than I thought.

The same process should work for the Bluetooth serial module, hoping to do a semi-permanent down at the ecm if that works out. Neat.

First drive of new injectors
Still have a small miss fire.. will try some fresh BPR6EF plugs after a visit to town this evening.. hopefully the tighter gaps will cure the last of it.
VS_SC_$51_Enhanced.adx req'd

Started better from cold, drivability seems 'normal' , but the BLMs are still a bit mad.. but too early to tell.

Was pleased to find out the plug gaps I want are off the shelf.

Cheers.

Note that ALDL is not J1850.

ALDL is also known as UART, is 8192 baud, and is on pin 9 which is not connected in your photo.

J8150 is also known as VPW and is one of many OBD2 protocols. Its the older one used by '0411 pcms.

You Sir are correct.

So I put the new plugs in today, such a difference in gap.

Old ones were some spare BPR6EFS-15's adjusted to 1.3mm... they've all opened up a bit to over 1.4mm, memory effect?

The new ones are just BPR6EF, they all measured 1.0mm inside the V-groove to the electrode as supplied.
Go for a drive a bit later see how they went, yesterdays logs showed the BLMs settled nicely- both banks seem happier.

Hopefully miss-fire cured.



Edit, Well that went well. Back to full power... use Clarksons voice for full effect.

lol!
