I also collected info about the Opel injectors:

-E85 capable
-working up to 350 bar
-around ~1400cc flow @ 100 bar
-can support 500+ hp with pump gas (depending if the hpfp flows enough)
-Can be used for minis and vw tfsi engines as upgrade
-part number: 0 261 500 112

I have finished the downpipe, the exhaust and fitted all the other missing stuff. I also fitted two catch cans. Here's a picture of the engine bay.

I let the car run for 20 minutes with various revs and did an oil change. Then I took it for a drive. The engine runs good with a few hiccups.

The logs showed that the engine runs to a lamda of 0.60-0.50 which is extremely rich. The bigger injectors have to be the cause of that.

Otherwise the car doesn't feel different except for the turbo. It surprisingly spools as fast or faster then the jcw turbo even with it's way bigger turbine and compressor. That thing took me by surprise as it spooled like there was no tomorrow.

Now it's time to get the ecu programmed.

Great work and mods on the car.

Are you using the OEM ECU or standalone and who is reprogramming the ECU for you?

Will you be putting the car on a dyno to see what power it makes when you're finished?

Are the injectors direct plug & play replacements or do they need modifying to make them work?

Iam using the oem ECU, a Delta ecu would cost a huge amount of money and is (in my opinion) not necessary for my power levels and modifications.

Fotis from revlimit is going to setup my mapping for the ecu.

They rail has to be modified to fit them because they have a plastik Pin to keep them in position.

The mapping has to be adjusted, because the injectors have way bigger flow then the stock ones.

The engine runs, but very rich lamdas up to 0.55 at load.

Yes Dyno numbers will soon follow when the mapping is ready!

hello, very nice project

i'm looking for information for my project so i have some questions

this in the PSA prince engine ? ( ep6 series)

for a simple stage 1 + e85, do the hpfp need to be swap ?

the modification on the rail for fitting the new injectors is simple ?

Very thx

It's the psa engine.

The railmod is quite easy.

I have no experience with e85, but the hpfp probably won't flow enough fuel.

very thx for informations,
do you know any model that will swap easily for the hpfp ?

 

[arke]

No unfortunately there isn't one.

Any news ?

I had some problems with the ecu and had to send it to Greece. It arrived again today, so I can start logging and get it done tuned.

What's in Greece and the ECU ?

My ecu software developer. The mapping is done by revlimit.

First Logs with the base map. The diagram below is a fourth gear pull from 1500 to 6700 rpm.

Full boost is at only 2300 rpm. What's really noticable is that the fuel pressure drops as soon as the boost comes at low rpm.

Looks like the stock pump already reached it's limits. The pump isn't spun fast enough at low rpm to keep up with the fuel demand.

The new pump solution has to come soon.

The development of the final software does last a bit longer then I thought.

Especially because the battery died on me and i had to replace it. Instead of an 55aAH i went to an 80AH battery.

The oil has to be replaced again. I found an oil I wanted to try, especially because it is sn+ specified.

There is an event next week on the GP part of the Nürburgring, so I thought i would be great opportunity to fit my suspension upgrades.

So the development of the mapping last more then I like it...

Mainly because of a few issues that needed to be sorted out.

The problem is that I get the P1947 code. I checked everything for leaks and my valve cover is new.

I can't find any leaks.

The only "leak" would be the blow off valve, which vents to the Atmosphere.

Any idea what the culprit could be?
