EFI PARTS FOR TUNING

[that_civic]

Has anyone used these for mapping ?
Loads of good reviews but mostly Renault from what I've read with a couple Hondas.

I was hoping to get romain to map mine but he must be the busiest person in the world haha so looking elsewhere that aren't miles away from me.

Already used a reputable company before and it drives like dogshit and believe I paid far too much so won't be going there again ( no names mentioned )

You won't go wrong with EFI.
There may be other options you'd consider in afew months time.

Chris is my hero.
I had my vx220s on the dyno there, he tuned my b18c on s300 from the ground up, and he dyno'd and will be tuning my Exige with K20A2 on Dta s60.

He also has a few week to a couple of month waiting list.

What did your b18 make out of curiosity and the spec ? How's the driveability on all the cars ?

Every decent tuner seems to be very busy lately haha

Without knowing your story I'd say your drivability issues are likely parts related more than the tune?

It ran fine before the tune on the stock ecu with the same mods apart from the injectors obviously . After the tune I've had nothing but issues. A few months back when helping a friends ecu issue we swapped ecus, put his c4 mapped p28 in mine and that actually made the idle better obviously any throttle because of the larger injectors made it big down, the cold start worked as well so I've actually got it down to a very bad or somethings gone terribly wrong within the ecu or map itself but I won't know so want someone who knows what they're doing to have a look and remap it.

But it left the original tuners all running fine?

This is the thing, he said test drive it after being finished, it drove fine ,in my opinion didn't really seem quicker or any smoother tbh just vtec lowered.
Returned , paid him his money, got on my way, about 30 minutes into the drive it would drop all revs for a mini second on partial throttle every time causing me to jerk back and forth, went to the services to grab a drink, came back and took forever to start . When it started it would hunt unless I caught the biting point then it would idle, this still happens to this day.

Next couple of days rang him up told him the issues he said it could be my lamba sensor , no idea how but bought a brand new one , same issues still. Rang him again he remoted in and saw my tps values had changed so adjusted them but after that it drove **** since and said he will have to charge me for anymore changes and will probably need to have my car again and possibly for a few days which wasn't convenient for me as he's about 150 miles from where I live and it's my only car.

He was thinking your lambda was cocking up the light load fueling, causing the stumble. Clearly wasn't the case...
I think you've got a parts issue somewhere, i woukdnt have thought a simple tps recalibration in the software would cause the car to run ****. Have you tried a spare one? You had tps issues due to wiring before didn't you?

Tried 4 different TPS sensors now lol
1 bwr that it was mapped on failed
2 genuine Honda ones that worked
And a replacement bwr that worked

We solved the TPS issue in the end , was down to the d series plug I used has a different pin out to the b series which I was unaware of when swapping the damaged b series to the d series plug. It's now slightly out of calibration about 0.52 closed 4.7 wot but is driveable, going to calibrate it in a couple of days to get it closer.

One more thing to point out, even before the TPS issue and after mapping it's over fuelled dumping black clouds out on overrun, my oil stinks of petrol.

 

[jesse888]

You could possibly try to oval the mounting holes for the TPS to give you that bit more adjustment....
Yeah that's not ideal to have it so rich your contaminating the oil.
