got my car booked in for rolling road tune on saturday checked water and oil anything else i need to check? and wat sort of power can i be hoping for with ofac 195 chip bieges, t2 cam, airtec front mount cooler ,exhaust, group a filter, standard t3 turbo and was told the head had been ported and polished but im not sure and no proof

 

cant answer you mate but im almost at that stage myself so would like to know also

 

is this a trick question.

You say you have a 195 chip. What are you expecting other than 195bhp. lol.

 

You are most likely to see around a genuine 185bhp'ish on a helthy engine and that spec, 195bhp is unlikely your turbo is your limiting factor.

 

At the full 16psi that the chip allows, would you think that power Karlos?
Thats the eventual spec of my engine, maybe with a kent cvh34/35 cam and stage 3 t3 tho.

 

Yeah around that I would think, with a port/polish and cam'd head it wont hold that boost till the limiter anyway, will only peek and then drop back a few psi, but it's all about flow...
My last engine for example made 186bhp on TOTD DD Dyno peeking at 16/17psi gradually dropping to around 12psi'ish as RPM increased, was low comp, ported head, piper 285T2, stock T3, would of made a fraction more if I was stock CR of course.
Your stage 3 T3 will probably make over 200bhp at 16psi because of the larger exhaust housing.

 

Thatd be nice 200bhp... Mine peaks at 0.8bar and then drops back to around 0.6bar as the revs go up is this normal then?

 

dont forget to make sure your tyre pressures are right

 

You will always get a little peek yes although it wil be less at lower boost of course.
Good advice!

 

thanks guys hoping all goes well wat would your next buy be to get more power ?

 

Stage 2 T3, but then you'll need a new MAP sensor, bigger injectors and another chip to really make the most of it.

EDIT: Just noticed your on OFAC, I'm not sure this can run a bigger MAP sensor can it?

 

Karlos no it can't but the MAP sensor is good for whatever you throw at it really, the 16psi limit is in the ECU, needs to be mapped out - speak to Stu @ MSD.

Whats the next step up from beige injectors, that can be used with OFAC?

 

Ah sweet! Injectors, probably best to speak to Stu, I have no direct experience with OFAC so dont know, maybe Greys?

 

well had it set up and today at Power Engineering found out im massively underfuelling 1st run was 155bhp and was badly running lean and was told it would melt a piston in no time had a fiddle and couldnt get it fueling right took 195 chip out and was better but still not right the ecu was just not picking up signals properly so was advised aftermarket management it made 150 in the end without the chip but still on bieges but it was fueling a bit safer so ive checked the rs bible and all pins have been changed that should be as running the ofac management on xr3i efi loom has anyone else done the conversion and had similar problem and found a solution ? i would like to add a big thanks to Power Engineering as he did help and explain everything and even just charged me a power run only as he said he couldnt set much up as the problem with the management

 

no end of problems for you martin,
sorry things arent going smoothly

 

Sorry to here the results, at least you know not to kick its head in till its sorted out

 

sorry to hear that but whenits sorted it will be a totally different car anbd will be rapid!!!

 

didn't think you could run beige injectors without the chip??

 

dont suppose u saw mine down there a red erst went for a set up last saturday left needing new newman cam , lifters and remap although pe and ian were really helpful

 

If he is lean which he seems to be then running bigger injectors will richen things up a bit, not normal but he has a problem.

 

Martin, I had this problem when i changed my EFi Orion (Basically XR3i loom) to OFAC, took it to my local tuner who cured the problem, but don't really know what he done... It was something todo with the CO Pot not working, but it does now and the car drives fine on the road... Would like todo a RR session to see if its lean etc tho!

 

mine drove fine on the road with chip in pulled really well but it wouldnt last the way it was

 

i did mate was in garage

 

just hope i can sort the ecu out or will be expensive going to aftermarket which my budget dont really stretch to im glad the proplem was found before i did damage to engine

 

he did say its safe to give it a bit of stick now just a shame its not the power i expected but 150 is still a bit of fun in a escort

 

well had some good news a custom map can be put on a chip for me but now weighing up if its worth it or is standalone management the only way to go

 

trouble is you need the chip to run the beiges right. no chip just put the blue injectors back in or even better just get stu or ahmed to do you a chip then you cant go wrong

 

i had the same problem with a cab i converted running standard injectors,i changed ,fuel pump,ecu,map sensor,co pot and it still didnt run right and i broke it in the end

 

problem is its a 1900 engine so without chip its fueling good with chip its running very lean

if i get one of them to do me a chip will that need to be altered everytime i change the spec or will it just need a set up again

 

i heard about your problem mate i see jonesy alot from ukford he mentioned it to me

 

i Guess a 1900cvh will need more fuel than a 1600cvh... Hence y it was lean with the beiges, you probably want a custom chip for your spec m8!

 

You need a custom chip for a 1.9 speak to MSD!

Grant

 

yes this is wat pe advised just weighing up if its worth it or to save for megasquirt or something similar just a thought but could bigger injectors work ?

 

You need to check the wiring. If you use an EFi loom (one originally used with a NA 1AFA ECU) then you need to swap a pin around in the ECU plug.

If memory serves the pin in question is for the CO pot so could partly explain some of your mixture issues.

Have you checked the fuel pressure?
