Georgio Posted June 2, 2014 Share Posted June 2, 2014 Hello people. Story so far... a friend of mine owns an Escort mk4. At some point, and after seeing my conversion, he wanted to do the same transplant to his car. After some search, he found a reputable garage...500 miles away from where we live, and drove the car to them to do the transplant. They did a full refurbish of the engine prior to install it to the car, new shells, springs, gaskets, etc etc. Problem was that the garage that did the transplant, had no electrician... so they bodged the loom, connected the fuel pump to run continyously, had A LOT of corroded wires, "forgot" to supply the CO pot, running the engine with wrong wirring on the TPS, and some other nice things that I can write for days... it also "runs" on stock boost, with beige injectors, and has a Garrett T3 turbo. When he took it back after a fight with the garage, since they had it for 3 months almost and never finished it, he said that enough with that joke, I want my car back. Of course as you realise, they finished it in the fastest way they could,so he can have it, and now the car consumes petrol like it is a Volvo tractor, idles like f@@ck, stumbles at accelerating, some times when boost hits boost limit etc etc... When he took it back, I had a look and managed to fix most of the problems, I wirred a CO pot correctly, fixed the TPS wirring, installed a fuel pump relay to run the fuel pump from the ECU,unwrapped the loom to check for other faults etc etc. Car runs much more better now, boosts fine, he ordered a wideband to set it up, but my problem is that if it idles for some time it starts to hunt a bit. It is not missfiring, it sounds like it is going to turn off momentarily, but it comes back again. After 2-3 minutes it does it again and works fine too. I am thinking that perhaps the injectors are a bit bigger than what is needed and floods the engine at idle. I set the CO pot about where my setting is, I set up mine with a wideband, and did the same setting at my friends pot. It is a rough setting, when I made it a bit leaner it idled much much better but I didn't want to lean it more to avoid melting anything. I told him not to drive it till his wideband arrive and install it so we can set it up correctly, but it seems we are in the correct route. Is there any chance that the injectors could cause erratic idle, am I correct on thinking that way? Link to comment Share on other sites More sharing options...
Stu Posted June 2, 2014 Share Posted June 2, 2014 What chip is in the ECU? What MAP sensor? What ECU? Link to comment Share on other sites More sharing options...
Georgio Posted June 2, 2014 Author Share Posted June 2, 2014 Oh God... I'm idiot... lol.Sorry Stu, you are right... it is on OFAC, no chip, runs on factory specs... Link to comment Share on other sites More sharing options...
Stu Posted June 5, 2014 Share Posted June 5, 2014 Well the original calibration isn't designed for beige injectors, so good luck getting that running right. Link to comment Share on other sites More sharing options...
scottybo Posted June 5, 2014 Share Posted June 5, 2014 Could he not swap back to standard items or get the ecu mapped for those injectors? Link to comment Share on other sites More sharing options...

scottybo Posted June 5, 2014 Share Posted June 5, 2014 there we go then, problem solved lol Link to comment Share on other sites More sharing options...
Georgio Posted June 5, 2014 Author Share Posted June 5, 2014 Thank you both of you for your answers... what I thought from the beggining was that beige injectors are a tad big for factory specs, and this is why it can;t idle as it should, it runs rich.I thought to find and install blue injectors, this is what came with from the factory. I just wanted a second opinion.Mapping is in the plans for the future, but first he wants to run it under oem specs... worst case scenario is to take off mine, I run mine on blues, and have a test fit to my friends just to test... but it is too much for a job just to check... what is funny is that on the cosmetic side, it is very good for everyday car... it is not for shows... he payed a lot of money, and he doesn;t drive it since it consumes way too much and doesn't run properly... here it is as it is now...http://img.photobucket.com/albums/v205/Georgio59/CFH%20meeting%20%2028-4-2013/100_2660_zpsf14147bc.jpg Link to comment Share on other sites More sharing options...
scottybo Posted June 10, 2014 Share Posted June 10, 2014 as above mate, tell him to get the ecu mapped to suit the bigger injectors, i could only assume he would gain a few hp along the way as well Link to comment Share on other sites More sharing options...
Georgio Posted June 11, 2014 Author Share Posted June 11, 2014 Yeah, it's in the plans. He also bought a wideband from AEM, I will install it on Saturday and have it setup. Well as far as I can set it up with beiges. It will never idle correctly till he finds a set of blues or a chip, but at least he can drive it for starters...

Stu Posted June 12, 2014 Share Posted June 12, 2014 Well, it's not on a T2 turbo anymore is it? So it's not standard. It's never going to run right unless everything is 100% standard and in good working order. Get a chip from someone like Ahmed Bayjoo for your spec. Should be relatively off the shelf for a standard engine, T3 and 701's (beige injectors). Link to comment Share on other sites More sharing options...
Georgio Posted June 12, 2014 Author Share Posted June 12, 2014 Thank you very much Stu for your advice, and everyone else who contributed, really appreciate it. No, it is not on factory specs, you are right. Unfortunately at this time he is a bit skint from various garages trying to find problems without having success, although he paid for it, unfortunatelly this is how they work here, you have to pay their time and for now he can't afford buy a chip. Further that, due to family issues he will pospone it. I will just set it up to the correct AFR ratios under boost and idling, at least the best I can under these specs, I intend to set it at around 11.5 - 12 under boost and 14.7-15 idle and test it for a couple of days. And with the first opportunity I will advice him to chip it. Link to comment Share on other sites More sharing options...
