Size of Sport300 primary and secondary injectors?

[Sparky]

It's a no-brainer that smaller balls will provide greater penetration.

[Chillidoggy]

Yes, but surely would larger balls spread their load over a bigger area?

[Sparky]

Indeed, but one must be mindful that, without proper control, they may be inadvertently banged into undesirable places adjacent to the target area.

[Chillidoggy]

Ah yes, I hadn't considered that.

It really needs someone else to hold it in place while you bang it in.

It's much easier to change out the standard for to an after market type, and that's  just what I did. I cut the fuel rail just before the FPR and welded on an An6 "weld on fitting" onto this I connect a raising rate adjustable FPR with built in gauge via some AN 6 fittings and braided hosing all for less than a €100. At least now I can fine tune my fueling with the rest of my mods.

Ian: Ah, okay, I get your point

I will certainly measure mine. The standard as well as the severely expensively one I bought.

So, I already went out and bought an adjustable kit from R&B. That demands a drilled hole in the inlet plenum chamber, and I am not willing to do that on my standard original one. So, I also went out and bought another of those, and that showed up to be something interesting. A project plenum chamber from 94'. More on that, when I fond out more.

The new one have a gauge as well.

Some sort of scheme of how much does what, would surely be nice.

Kind regards,

Jacques.

This is just a maybe, as I haven't had it confirmed anywhere:

The SE/S4 may run the fuel pressure at around 3 bar at idle.

The Sport300/S4s may run the fuel pressure at around 4.3 bar at idle.

This is btw. what R&B writes in the installation manual for their adjustable fuel pressure regulator.

I installed the Sport300 fpr today and took it out for a run. Well, it's a bit hard to say, but at least the Esprit Turbo SE shoots forward pretty fast compared to before and holds boost a lot longer and with less "downtime" so to say.

So, to get to my question: I'd like to finalise this by installing the new Bosch fuel pump in the right side fuel tank. To do so, I took off the carpeted cover, and took a look. There seems to be some unbraco bolts (9) holding some sort of retaining plate, which again holds the fuel tank top cover with the two fuel hoses/tubes passing through it.

Since I have the wooden board above the aluminium fuel tank, I cannot readily access all of the bolts. How do I reach those?

Kind regards,

Jacques.

[Vulcan Grey]

you do not need to remove bolts to remove the pump!

 

You only need to knock the locking ring around in the Counter Clock-Wise direction (CCW).

Use something non-sparking like wood or plastic.  Also you should spray some lubricant on the locking ring to help the o-Ring release. I used WD-40.

 

[Jacques]

Super nice Travis! Thanks a ton.

I'll do that tomorrrow then.

Since I just relearned the ecm some data the other day after having installed the new ecm and turbo, do I need to relearn it again after changing the fpr and fuelpump? Or is a normal drive without first taking off the battery enough?

Kind regards,

Jacques.

[Vulcan Grey]

I would remove the ECM fuse to allow the ECU to re-learn.  Just don't disconnect the battery or remove the fuse while the keys are in the ignition!

[Vulcan Grey]

@Jacques do you have a wide band Air Fuel sensor?  It can of course be dangerous to change fuel settings without one to monitor the actual A:F.

I have a PLX Devices wideband sensor, I also have a boost sensor and a dual coolant temperature sensor, all on the same gauge.

I am wiring my '88 CIS Injected car with this comprehensive DIY System.

Similar, but much simpler (just SCG-1 + PL-1) is going on my S4s when I switch to Red Chip.

Any comments/suggestions?

The SSI-4 PLUS captures data from 4 external sensors. These sensors can be frequencies such as engine RPM and speed sensors or 0-5V references like MAP sensors and pressure transducers. The SSI-4 PLUS may be used as a stand-alone system or integrated with other Innovate Motorsports MTS products to create a log chain. The SSI-4 is also a key component of Innovate Motorsports' Modular Tuning System (MTS). Using the SSI-4 PLUS's serial ports you can daisy-chain other Innovate devices such as the MTX-L, LM-2, LC-2, and TC-4 PLUS.
