hi i have just bought a 130ps maf ecu and throttle body from a member on this forum. i was just wondering what is the difference between a 105ps maf and throttle body and a 130ps ones as i have checked the sizes of the 105 maf to the supposed 130 maf and they are exactly the same is it the sensor which is different rather than the size. i am yet to check and compare the throttle body i just hope i havent bought 105ps stuff. any help apprecieted thanks in advance guys

[edders]

well the maf and ecu arent really the parts that make it 130PS. you will also need a set of 130 spec cams or i believe the 2 ltr ones work just as well.

[hartyfezzy]

i am aware that i need the cams as well but still looking for some at a good price. just wanted the info about the parts i have as there isnt a difference in size between my 105ps maf and the 130 maf i have just bought. the ecu is deffo a 130 ps one as the code is 2fbc which i believe is from a mk5 escort 130ps. any1 else who can help? thanks

The throttle body will be bigger if it from a 130ps model. 1800 MAF are all the same as are the injectors. You'll need a HO inlet fanimold as well. What year are you putting into, I hope you've bought the right ECU.

[matty872]

You can use a 2ltr maf or I belive an escort gti one as they are much bigger than the 2i ones.

NO, the MAF has to be matched to the ECU.

[Oranoco]

DOn't forget that after you've sourced all thes parts you won't actually have 130PS but will typically have about 120-125.

As Olly says, the MAF has to be matched to the ECU. Your original one would have been fine, as the one you've bought will the same. The 2.0 (and 1.6 and 1.8 Mondeo ones) and 115PS Escort ones will not work correctly on the ECU you have bought.

ok thanks for your help guys. i got bit worried when i compared the mafs and there was no difference thats all. any advise on what cams to get? i understand 2.0 cams will work but have read they have 1degree higher lift or something will this not make it run dodgy? thanks again

[Oranoco]

We've had good results using Piper reprofiled fast road cams

[hartyfezzy]

cool. i will look into them. which cams would be better to use out of the 2.0 ones and the 130ps ones. if i used the 136ps 2.0 ones would the added ps actualy be put out by the car or would it run funny?

[Smo]

The cams are pretty much identical. If you look in the guides forum for the cam topic, you'll see right at the bottom some research of mine regarding part numbers

[hartyfezzy]

thanks guys i put my tb on yestarday and the opening at the butterfly is much bigger on the 130ps one i was surprised at the difference. i think i will be looking to get the 'ho' manifold after saving up some cash if the size difference is anything like the throttle bodies must be so restrictive. thanks

[Smo]

I would do the cams and ECU before the inlet manifold and see how you find it. The inlet only really helps the top end power, but tends to kill a bit of the lower down torque. In my opinion it makes the car less fun to drive and has to be driven harder to get the benefits. I'm even considering putting my SO manifold back on to enjoy day-to-day driving more.

[hartyfezzy]

ok smo thanks for that i do remember reading that on a post somewhere befor. i cant wait to get some cams and get it all running 130ps (really probably only 120 if im lucky) but its better than nothing i suppose.

hey buddi.. just a wonder.. but hows ur car doing on the new stuff... im currently undergoing 105-136 ps change...replaced throttle body, maf sensor and coil pack... but having no luck finding the right ecu... i cant find one that will turn over the engine..and im yet to get my 2.0 mondy cams in the car too... anyone got any ideas as to whats wrong with the ecu thing.. ive tried about 4 ecus.. ranging in codes from taxi to beep and deer.... oh its driving me mad.. cuz im still probab;ly running at 105 without the brain (ecu) telling the parts to use more fuel and air... aarrrgggghhhhhh

[Smo]

Firstly, it's 130PS - And with that, the most you'd possibly see would be about 128bhp, however most only see about 123 to 125bhp (although there's not much in it).

MAF sensor and coil pack don't need changing when using a proper 1.8 130PS ECU.

It sounds like you're just using any old 2.0 ECU that you can find - bad idea! For starters, your XR2i 16v uses external EDIS, which means you need to use an external EDIS ECU (no manual 2.0 ones exist). The only 2.0 ones that work on a Fiesta engine loom are DEEP, DESK and DEWY (at least, they're the known ones), however they use an internal EDIS module (i.e. built into the ECU) and only work on the Fiesta engine looms which don't have the external EDIS module connector.

You need a 1.8 130PS ECU that is for use on an engine loom with an external EDIS module. From the top of my head, compatible ECUs are ALSO and 2FDC (both from early RS1800s), however others do exist.

If you do want to use a 2.0 ECU (such as the ones mentioned above - also with which you then would need to use the 2.0 MAF), you will need to change your engine loom for one that uses internal EDIS (e.g. Fiesta 1.6 Si 16v), or modify your engine loom - for a guide, see Scort's EEC-IV topic in the guides forum

[XR2i dude]

right..... wen my car was rr tested about 3 months ago it was running 110 bhp with no engine alterations apart from air induction... i havent since tested it since the 2.0 modifications... i have the 2fdc ecu you speak of in my car when i brought it.. since then i have been running a friends 1.8 ecu with collins chip attached... but i thought this whole upgrade was 2 a 2.ol mondeo spec... which is 136 ps..... why if im running 2.0 components would i want 1.8 management??? i thought the whole idea was to increase the air and fuel consumption(the basic principles of going faster) from a 1.8 to a 2.0, hence the larger maf, larger throttle body, higher lift cams, greater spark production and of course the brain (ecu) to tell these components to do these things... basically running 2.0 without the actual bore size....

could you please tell me a bit more about the external and internal edis module please.. as i feel that this may be what is stopping my 2.0 ecu conversion....
please please correct me if im wrong... this is my first xr and im just going by what seems logically right... by increasing the 2.0 136 ps.... i cant see why using a 1.8 ecu will be sufficient for all 2.0 parts..?

[Ollybee]

But you're still running 1800 engine??

[XR2i dude]

yes... until i save the ££ for a 1.9 cvh tubby conversion..

[Ollybee]

So you are doing an RS1800 conversion. Use 130ps bits. If you get it rr'd again and it's pulling 120hp your a lucky man. Use the ECU's that Smo has suggested and it will run.

[XR2i dude]

no i was doing the 2.0 mondeo conversion not an 130ps rs1800 hence why ive used all the 2.0 parts... i knew about this before i read this post and before i knew about the 1800rs conversion... so ive been doing this mondeo conversion for a while with ill advised advice to be honest.. so i thought it was time to get sopme proper direction finally.... ive modified the throttle body to fit.. done the maf and coil pack.. cams are about to go in.. but now im thinking that the ecu wont work until ive done this internal edis function...so im running a 1.8 chipped ecu at the moment... i have this 2fdc ecu that he says is from a rs1800.. it was in my car originally.. but will it be sufficient to run 2.0 136ps components??? i mean my 1.8 ecu is running the car now.. but not to the ps i was wanting.. will the 2fdc ecu make any diff???

[Ollybee]

If you've got a 2.0 in it then you need to run the deep, desk, dewy ecu with the proper pin changes. There is a guide in the guides section for this exact conversion.

[Smo]

The thing is, you're running a 1.8 still. The 2.0 parts you're talking about are pretty much identical to the 1.8 130PS parts, so by fitting them, you're only really doing a 130PS conversion... Not a 2.0 conversion. Your displacement is still 1800CCs and therefore it cannot produce the power (and definitely not the torque) of a 2.0 for the given modifications, therefore 2.0 management is not ideal for your setup.

The 2.0 throttle body is the same size as an RS1800 and the cams are 99.9% identical (people say they're different, but having checked out part numbers, the 2.0 cams are actually the same as used in the RS1800).

[Ollybee]

I think we need a score sheet for how many times the RS1800 conversion question gets asked this year.

[XR2i dude]

ok smo.. thats basically answered my question... so ill be fine running the 2fdc rs1800 130ps ecu then.. if the other components are similare to that of the rs1800 if not the same then itll work fine on that ecu then?
