Hi, a workshop is changing the engine in my st205, and they have given me an offer to change the ecu to a haltech stand-alone and remap it for a total of about 900£ extra. Do you think this will be worth it? They will be putting in a Spec stage 3+ clutch while they're at it.

Finally, the car has been mapped, but i suspect it is not optimal. Its harder to start, uses more fuel and its useless below 1500rpm. I talked to the mechanic about the last problem, and he just answered " youre not supposed to drive at 1500, so it doesnt matter".
When cruising the AFR shows 10-12. Same conditions with the stock ecu it was around 14-15. If i slowly apply the throttle when driving below 1500rpm, it suddenly jerks forward. Above 3krpm it has got way more power, but drivability has taken a serious hit. This post has been edited by skogs: Sep 12, 2014 - 5:14 PM |

I can't tell from the previous posts if you only did the road tune but I would recommend a proper dyno tune. When it comes to tuning the car it's worth the money to have it done right and by a well known and experienced tuner. I hope you get it resolved! I plan on going with a standalone as well so I am definitely interested in your setup! -------------------- 1994 Toyota Supra RZ - Weekend Warrior - 715rwhp
