Interesting. I always have 1/2-3/4 tank level od petrol, that is cca 30-40 litres. Every month i put cca 10 litres of fresh 100 octane petrol.
Technical Fiat Bravo Problems wit first starting the engine

Technical Fiat Bravo Problems wit first starting the engine
Hi
I know I'm writing in an old thread, but I didn't saw a solution for the problem and ... here I am
I had absolutely the same problem with Fiat Bravo MK2 1,4 with LPG
The first start of the engine was awful (the car started after 3-9 retries ... )
A few days ago I finally found a solution - to delete the adaptations on the ECU
According to the worker in the service shop, if the adaptation is more than 20% far from the genuine value, the ECU cannot revert the adaptation by itself, and the problem persists until the adaptation is deleted.
In my case, after the adaptation was deleted, I drove 200 km on gasoline to allow the ECU to make a proper adaptation. After this, the car is starting without any issue (like a new car)
The last step is to make new settings on the LPG system (because the old settings were based in the bad adaptation) - this was also recommended by the worker in the service shop.

That meas your LPG system was improperly calibrated.
On my car the adaptive parameters always stay +/-3% (5% up to 5% is acceptable) .
Still have the cold start problem with petrol that sits too long in the tank.
After i consume that, and add new petrol. there is no problem.
In my case, when the LPG system was installed, they started automatical settings, and everything was OK. in one month I went to the service center to check the settings (our service shops recommends one month after the new LPG system is installed to make new settings on the LPG system). They checked the settings and manually manipulated (not more +/- 5%), and from this moment the problem came up ... I changed the spark plugs, check the cables, errors, temperature sensor ... nothing.
The procedure with the adaptation fixed the problem. From this moment I did not add more fuel. With the fuel that I had the problem, after the procedure, the car is starting perfectly.
About the percentage - I don't know if the +/- 3% is acceptable, but if in some case (for example bad LPG fuel) the parameters are not OK, and the car ECU are trying to fix the problem with adaptation, and there is no result, maybe the injection time will pass 20% more or less ... I'm guessing now ...
In my case, the service worker was familiar with the issue, he explained to me this, and after the adaptation was deleted, the first cold start is OK.
If you have a problem and can delete the adaptation - you can try. The procedure is not expensive.
Unfortunately, I did not manage to find instructions on how to delete adaptations by myself (there is a lot of cheap cables for Autocom, multiecuscan, ...)

Sorry, maybe its a silly question, but who can delete those adaptations: someone with a Fiat interface or the guys that installed the LPG on the car. I have the same problem with a Bravo 1.4 90hp with LPG.
Hi there,
the adaptations can be deleted from someone with Fiat interface.
The guys that install LPG, in general, do not have the proper interface and knowledge to do this operation.
Dear All,
I have the same problem with two T-Jets in the family.
However, our cars are non LPG ones, just the plain petrol T-Jets.
One is the 150hp and the other one is 120hp.
Has anybody ever found solution for the hard starting?
It is related to how long the car settles. If the engine is off for overnight and the outside temp is below 15°C, then next morning the hard starting is highly possible.
Occassionally the ignition failure error code comes on, but that is not the root cause. Spark plugs were changed, timing sensor was changed, oil separator box was changed - no improvement.
Anybody ever experienced such?

Try to refuel with high octane fuel. more than 98. i fix the problem with this. no issue for 4 years
why do all normal cars fill up 95, and I have to fill up 98 in this **** ?
Replace the petrol injectors micro-filters, they get dirty and clog up.
It's more noticeable on LPG cars, because petrol stands on the tank longer ant it looses its volatile components before the petrol gets burnt. That's also why you get this problem at first start on cold mornings and also why the cars gets better when you put some new petrol in.
Try it!

is this a permanent solution?
Thats how i use it, if the fuel tank goes under half full, the car takes around 5 minutes to start every morning.
